Chlorophylls Extraction from Spinach Leaves Using Aqueous Solutions of Surface-Active Ionic Liquids was written by Ferreira, Ana M.;Leite, Ana Claudia;Coutinho, Joao A. P.;Freire, Mara G..

Chlorophylls and their derivatives have been extensively studied due to their unique and valuable properties, including their anti-mutagenic and anti-carcinogenic features. Nevertheless, high-purity-level chlorophylls extracted from natural sources are quite expensive because the methods used for their extraction have low selectivity and result in low yields. This study aimed to develop a “greener” and cost-effective technol. for the extraction of chlorophylls from biomass using aqueous solutions of ionic liquids (ILs). Several aqueous solutions of ILs, with hydrotropic and surface-active effects were evaluated, demonstrating that aqueous solutions of surface-active ILs are enhanced solvents for the extraction of chlorophylls from spinach leaves. Operating conditions, such as the IL concentration and solid-liquid ratio, were optimized by a response surface method. Outstanding extraction yields (0.104 and 0.022 weight% for chlorophyll a and b, resp., obtained simultaneously) and selectivity (chlorophyll a/b ratio of 4.79) were obtained with aqueous solutions of hexadecylpyridinium chloride ([C16py]Cl) at moderate conditions of temperature and time. These extraction yields are similar to those obtained with pure ethanol. However, the chlorophyll a/b ratio achieved with the IL aqueous solution is higher than with pure ethanol (3.92), reinforcing the higher selectivity afforded by IL aqueous solutions as viable replacements to volatile organic compounds and allowing the obtainment of more pure compounds Finally, the recovery and reuse of the solvent were evaluated by using a back-extraction step of chlorophylls using Et acetate. The results disclosed here bring new perspectives into the design of new approaches for the selective extraction of chlorophylls from biomass using aqueous solutions of surface-active ILs. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.SDS of cas: 75-57-0

The extraction mechanism research for the separation of indole through the formation of deep eutectic solvents with quaternary ammonium salts was written by Jiao, Tiantian;Ren, Chuhan;Lin, Shaojie;Zhang, Lianzheng;Xu, Xianzhen;Zhang, Yaqing;Zhang, Wenrui;Liang, Peng.

Indole is an important industrial substance that can be derived from coal tar. However, traditional acid-base separation method causes serious environmental problems. In this research, the indole separation abilities of different quaternary ammonium salts (QASs) from nitrogen-containing compounds and azeotrope systems were explored. Series of QASs with different substituent groups were investigated through examining the extraction efficiency, including tetraethylammonium chloride (TEAC), betaine hydrochloride (BHC), tetramethylammonium chloride (TMAC), tetraethylammonium bromide (TEAB), and benzyl trimethylammonium chloride (BTMAC). Among them, TEAC was found to be able to form deep eutectic solvents (DES) with indole. The effects of different exptl. conditions such as extraction time, extraction temperature, and mole ratio were studied and optimum extraction conditions were obtained. Quantum calculation was employed to explore the extraction mechanism. σ-profiles and σ-surfaces of QASs ions and related compounds were derived from COSMO database and analyzed to explore their interaction forces. The interaction energies between QASs ions and related compounds composed by misfit, van der Waals (VDW) and hydrogen bond (HB) were calculated based on COSMO-RS theory. Using these methods, the separation possibilities of indole through DES formation by QASs can be speculated. Ultimately, the bond lengths and interaction energies between QASs and indole were calculated concretely using Material Studio. The above quantum calculation proved the existence of hydrogen bonds between indole and QASs and the deductions obtained from quantum calculation were consistent with the exptl. results. According to the above anal., the separation method through DES formation was proved to have a relatively high requirement for extractant. The mechanism research in this article provided essential reference for the selection of applicable extractant, and the prediction of the separation efficiency. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0COA of Formula: C4H12ClN).

Speciation of Ionic Uranyl-Containing Complexes in Situ Formed Dicyanonitrosomethanide-Based Ionic Liquids was written by Hou, Xiaomin;Tang, Si-Fu. And the article was included in Inorganic Chemistry in 2021.HPLC of Formula: 75-57-0 The following contents are mentioned in the article:

It was found that the dcnm anions transformed into ccnm anions during the reactions. These anions coordinate with the uranyl cations in chelate or terminal monodentate coordination mode, affording neg. divalent complex anions which can combine with different organic cations and form ionic uranyl-containing complexes. Plenty of C-H···O, N-H···O, C-H···N, N-H···N, and H···H weak interactions are formed in the crystal structures. The transformation of cyano to amide groups contributes to the crystallinity and leads to higher m.ps. as well as the luminescence quenching of these compounds The speciation of uranyl-containing ionic complexes in in situ formed dicyanonitrosomethanide-based ionic liquids was investigated. Four ionic uranyl-containing complexes with varying organic cations and complex anions were successfully obtained by competing coordination and metathesis reactions. Some of the cyano groups in the ligands hydrolyzed to amide groups, contributing to the formation of many weak interactions and crystallization The thermal stability, phase transition behaviors, and photophys. properties were also investigated.

This article investigates the applicability of an environmentally friendly and energy efficient deep eutectic solvents (DES) for indigotin blue dye (IBD) preconcentration prior to its quantification by a UV-Visible spectrophotometer. The adsorbent (UT-mGO) is made of Fe₃O₄, graphene oxide, urea and tetramethylammonium chloride. It was prepared via dispersing magnetic graphene oxide in a DES. The adsorbent was prepared fast and easy, without consumption of dangerous reagents. The X-ray diffraction patterns show pure structures of components. The FT-IR spectra show strong interaction between DES and mGO. In addition, a scanning electron microscope confirms that DES covered the surface of mGO homogeneously. Magnetic amount and surface property were characterized by an alternating gradient force magnetometer and Brunauer-Emmett-Teller, resp. High surface area and enough magnetic property, as well as π-π and electrostatic interactions among analyte and adsorbent propose UT-mGO as a qualified candidate to preconc. IBD. Effective parameters including pH, adsorbent amount, adsorption time, eluent and desorption time were optimized. Under the optimized conditions, the method has the following figures of merit: (a) limit of detection of 1.5 × 10^-6 g L^-1, (b) relative standard deviation (n = 7) of 3.49%, (c) preconcentration factor of 50 and (d) linearity of dynamic range of 1.0 × 10^-5 to 45 × 10^-5 g L^-1. The adsorbent is not reusable but durable in six months. Isotherm model of Langmuir and kinetic model of pseudo-second-order fitted for the system. ΔH (-13.2 × 10³ J mol^-1), ΔS (5.38 J K^-1 mol^-1) and ΔG (-3.69 × 10³ – +10.9 × 103 J mol^-1) were calculated as thermodn. parameters.

Mixed Solvothermal Synthesis of Tn Cluster-Based Indium and Gallium Sulfides Using Versatile Ammonia or Amine Structure-Directing Agents was written by Sun, Meng;Zhang, Shu;Wang, Kai-Yao;Wang, Juan;Cheng, Lin;Zhu, Jia-Ying;Zhao, Yi-Ming;Wang, Cheng.

Metal chalcogenide supertetrahedral Tn clusters are of current interest for their unique compositions and structures, which rely highly on the structure-directing agents. Herein, we report four novel Tn cluster-based indium and gallium sulfides, [NH(CH₃)₃]₄In₄S₁₀H₄ (1), (NH₃)₄Ga₄S₆ (2), [NH₃CH₂CH₃]₅(NH₂CH₂CH₃)₂Ga₁₁S₁₉ (3), and [NH₃CH₂CH₂OH]₆Ga₁₀S₁₈·2NH₂CH₂CH₂OH (4). All four compounds were solvothermally synthesized in mixed amine-ethanol solutions or deep eutectic solvent (DES), where ammonia/amine mols. play significant structure-directing roles in the speciation and crystal growth. (1) Being protonated, the trimethylamine and ethanolamine mols. surround the T2-[In₄S₁₀H₄]^4- clusters (for 1) and [Ga₁₀S₁₈]_n^6n- open framework (for 4), resp., compensating for the neg. charge of the inorganic moieties. (2) With the lone pair of electrons, the ammonia mols. in 2 coordinate directly to corner Ga³⁺ ions of the {Ga₄S₆} cage to give a neutral T2-(NH₃)₄Ga₄S₆ cluster. (3) For compound 3, part of the ethylamine mols. act as terminating ligands for the T1 and T3 units in the [Ga₁₁S₁₉(NH₂CH₂CH₃)₂]_n^5n- layer, while the rest act as interlamellar countercations upon protonation. Theor. studies reveal the contributions of N, C, and H to the d. of states (DOS) for 2 and 3 because of their hybrid structures that combine the ammonia/amine ligands with sulfide moieties together.

Layered Inorganic-Organic 3,5-Dimethylpyrazole-4-Sulfonate Films for Protection of Copper Surfaces against Corrosion was written by Al Isawi, Wisam A.;Jianrattanasawat, Sarut;Tripodianos, Eleftherios;Demadis, Konstantinos D.;Kirillov, Alexander M.;Zeller, Matthias;Mezei, Gellert.

A series of 11 compounds, including alkali (Li, Na, K, Rb, Cs) and alk.-earth (Mg, Ca, Sr, Ba) coordination polymers, transition-metal (Cu, Cd) complexes, and the ammonium salt of 3,5-dimethylpyrazole-4-sulfonic acid (HL), were synthesized. Single crystals of HL·H₂O, LiL(H₂O), NaL(H₂O), RbL, CsL, CaL₂(H₂O), SrL₂(H₂O), BaL₂(H₂O), CuL₂(H₂O)₃·2.3H₂O·0.5(acetone), and CdL₂(H₂O)3·2H₂O were obtained from aqueous solutions either by evaporation or acetone vapor diffusion. Characterization by single-crystal X-ray diffraction reveals that the coordination compounds of L- (except Cu) possess alternating inorganic-organic layered structures, in which L- engages in extensive charge-assisted networks of H-bonding and aromatic interactions as well as metal coordination through the pyrazole N atom and/or the sulfonate O atom. A topol. anal. and classification of underlying metal-organic or hydrogen-bonded networks uncover a number of distinct topol. nets (3,5L2, hcb, 6,6L1, 3,5C1, 3,8L28, hex, and pcu). A thermogravimetric anal. shows that HL and NH4L are stable up to 285 and 90 °C, resp., whereas the anhydrous metal compounds decompose above 200-230 °C. The pKa values of 3,5-dimethylpyrazole-4-sulfonic acid (HL) and pyrazole-4-sulfonic acid were determined by 1H NMR titrations with H₂SO₄. Copper corrosion experiments indicate that 3,5-dimethylpyrazole-4-sulfonic acid (HL) is a better anticorrosion agent than the parent pyrazole-4-sulfonic acid at pH 4, whereas the coordination polymers of L- offer weaker corrosion protection in comparison to the corresponding pyrazole-4-sulfonate complexes. The latter result is corroborated by the less compact and less robust thin films formed by metal-L compounds, as indicated by SEM/energy dispersive X-ray spectroscopy (SEM/EDS) measurements, and the weaker acidity of HL, which allows for easier protonation of the conjugate base L- in metal-L compounds This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).

Conducting chiral nickel(II) bis(dithiolene) complexes: structural and electron transport modulation with the charge and the number of stereogenic centers was written by Abherve, Alexandre;Mroweh, Nabil;Cauchy, Thomas;Pop, Flavia;Cui, HengBo;Kato, Reizo;Vanthuyne, Nicolas;Alemany, Pere;Canadell, Enric;Avarvari, Narcis.

Ni(II) bis(dithiolene) complexes can provide crystalline conducting materials either in their monoanionic or neutral forms. The use of chiral dithiolene ligands with one or two stereogenic centers, together with variation of the counterion in the anionic complexes, represents a powerful strategy to modulate the conducting properties of such mol. materials. The chiral ligands 5-methyl-5,6-dihydro-1,4-dithiin-2,3-dithiolate (me-dddt) and 5,6-dimethyl-5,6-dihydro-1,4-dithiin-2,3-dithiolate (dm-dddt) were generated from the thione precursors (1) and (2) which were structurally and chiroptically characterized. Anionic Ni(II) complexes of these two ligands with tetrabutyl-ammonium (TBA) and tetramethyl-ammonium (TMA) were prepared and structurally characterized, suggesting that it is the nature of the counterion which mostly influences the solid state organization of the complexes. Both TBA and TMA radical anion salts are Mott insulators with antiferromagnetic ground states, as suggested by spin polarized DFT band structure calculations However, the TMA salts are one order of magnitude more conducting than the TBA counterparts. The neutral materials [Ni(me-dddt)₂] and [Ni(dm-dddt)₂] are direct band gap semiconductors, as determined by DFT and extended Huckel band structure calculations, with their conductivity drastically increased up to 0.05-3.3 S cm^-1 under the highest applied pressures of 10-11 GPa. At equivalent applied pressures the dm-dddt materials are more conducting than the me-dddt ones, in agreement with the lower calculated activation energy and larger bands dispersion for the former. This trend follows the structural change when going from one to two Me substituents, since the packing and intermol. interactions are completely different between [Ni(dm-dddt)₂] and [Ni(me-dddt)₂], the packing of the latter being related to the one of the achiral parent [Ni(dddt)₂]. Subtle differences of conductivity are also observed within both series of neutral complexes between the enantiopure and racemic forms. This represents the 1st series of chiral Ni bis(dithiolene) complexes which shows modulation of the conducting properties with the number of stereogenic centers, the conductivity, measured on single crystals, strongly increasing upon applying hydrostatic pressure. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Interaction of aqueous suspensions of single-walled oxidized carbon nanotubes with inorganic and organic electrolytes was written by Laguta, Anna N.;Mchedlov-Petrossyan, Nikolay O.;Bogatyrenko, Sergey I.;Kovalenko, Sergiy M.;Bunyatyan, Natalya D.;Trostianko, Pavlo V.;Karbivskii, Vladimir L.;Filatov, Dmitriy Yu..

This article reports the colloidal behavior of the single-walled carbon nanotubes, SWCNT, decorated by COOH groups, in water. Energy dispersive X-ray spectroscopy (EDS), XPS, and thermogravimetric anal. (TGA) methods were used to characterize the solid samples. The SWCNT suspension was characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM) methods, as well as taking into account the dependence of the electrokinetic potential ς on pH. The neg. charged particles with a diameter of an equivalent sphere about ≈ 200 nm possess a ς value of -48 mV at pH 5.7 ± 0.1. Deceleration of the reaction of cationic and anionic triphenylmethine dyes (methyl violet and nitrophenol violet, resp.) with hydroxide ion in the presence of the SWCNT was observed This effect can be associated with a lower local concentration of hydroxide ion compared to the bulk phase owing to a substantially interfacial concentration of the COO- groups. Critical coagulation concentrations, CCC, in electrolytic solutions were determined using the rate of increase in size. Coagulation with different inorganic electrolytes demonstrated that the system under study obey the Schulze-Hardy rule. Comparison with the literature data allowed confirming that the CCC for NaCl can be an effective criterion of oxidation degree of the carbon materials of this type. The coagulating influence of surface-active organic cations, including dyes, is much expressed. Besides the overcharging of the neg. charged colloidal species by cetyltrimethylammonium bromide, the same effect was revealed in the case of the cationic dyes neutral red and methyl violet, and even for the Ca²⁺ and La³⁺ cations. Methylation of the carboxylic groups, COOH → COOCH₃, of the SWCNT during 380 h, as well as heating up to 1000°C results in a substantial and sometimes opposite changes in the CCC values for different electrolytes. Along with decreasing in the CCC for NaCl, an increase in the corresponding values for multi-charged cations was observed This reveals the important role of the simultaneous interactions of multi-charged cations with several COOH (or COO-) groups in the case of the initial highly oxidized SWCNT, because this effect became less possible after methylation or removal of the carboxylic groups via heating. A substantial neg. ς-potential in aqueous media of the colloidal particles of preheated, i.e, devoid of carboxylic groups SWCNT, allows expecting an alternative charging mechanism, characteristic of oil drops and gas bubbles. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

Rational Construction and Performance Regulation of an In(III)-Tetraisophthalate Framework for One-Step Adsorption-Phase Purification of C₂H₄ from C₂ Hydrocarbons was written by Fan, Lihui;Zhou, Ping;Wang, Xinxin;Yue, Lianglan;Li, Libo;He, Yabing.

The development of porous materials for ethylene (C₂H₄) separation and purification, a very important separation process in the chem. industry, is urgently needed but quite challenging. In particular, the realization of selectivity-reversed adsorption (namely, C₂H₄ is not preferentially adsorbed) and the simultaneous capture of multinary coexisting impurities such as ethane (C₂H₆) and acetylene (C₂H₂) will significantly simplify process design and reduce energy and cost consumption, but such porous materials are quite difficult to design and have not yet been fully explored. In this work, by employing an aromatic-rich bithiophene-based tetraisophthalate ligand, we solvothermally fabricated an anionic In(III)-based framework termed ZJNU-115 featuring In(COO)₄ as an inorganic secondary building unit as well as one-dimensional channels. Due to the absence of unsaturated metallic sites, together with aromatic-rich channel surface decorated with abundant hydrogen-bonding acceptors of carboxylate oxygen and thiophene sulfur atoms, desolvated ZJNU-115 exhibited an unusual adsorption relationship with respect to C₂ hydrocarbons, namely, simultaneous and preferable capture of C₂H₆ and C₂H₂ over C₂H₄ at the temperatures investigated, thus representing a rare metal-organic framework (MOF) with the promising potential for one-step adsorption-phase purification of C₂H₄ from a trinary C₂ hydrocarbon mixture Compared to a few of the MOFs reported for such an application, ZJNU-115 displayed simultaneously good adsorption selectivities of both C₂H₂ and C₂H₆ over C₂H₄. Furthermore, its separation potential can be postsynthetically tailored by substituting dimethylammonium (Me₂NH₂⁺) counterions with tetraalkyl ammonium ions (NR₄⁺; R = Me, Et, or n-Pr). More importantly, ZJNU-115 was stable in various organic solvents as well as aqueous solutions with pH values ranging from 5 to 9, thus laying a solid foundation for its practical applications. The design principle and the performance regulation strategy adopted in this work will offer valuable guidance for the contrapuntal construction of porous MOFs employed for direct multicomponent purification of C₂H₄ with improved performance.

1.3 V Inorganic Sequential Redox Chain with an All-Anionic Couple 1-/2- in a Single Framework was written by Buades, Ana B.;Vinas, Clara;Fontrodona, Xavier;Teixidor, Francesc. And the article was included in Inorganic Chemistry in 2021.Recommanded Product: Tetramethylammonium chloride The following contents are mentioned in the article:

The relatively low symmetry of [3,3′-Co(1,2-C₂B₉H₁₁)₂]^– ([1]^–), along with the high number of available substitution sites, 18 on the boron atoms and 4 on the carbon atoms, allows a fairly regioselective and stepwise chlorination of the platform and therefore a very controlled tuning of the electrochem. potential tuning. This is not so easily found in other systems, e.g., ferrocene. In this work, the authors show how a single platform with boron and carbon in the ligand, and only cobalt can produce a tuning of potentials in a stepwise manner in the 1.3 V range. The platform used is made of two icosahedra sharing one vertex. The E_1/2 tuning has been achieved from [1]^– by sequential chlorination, which has given potentials whose values increase sequentially and linearly with the number of chloro groups in the platform. [Cl₈–1]^–, [Cl₁₀–1]^–, and [Cl₁₂–1]^– have been obtained, which are added to the existing [Cl–1]^–, [Cl₂–1]^–, [Cl₄–1]^–, and [Cl₆–1]^– described earlier to give the 1.3 V range. It is envisaged to extend this range also sequentially by changing the metal from cobalt to iron. The last successful synthesis of the highest chlorinated derivatives of cobaltabis(dicarbollide) dates back to 1982, and since then, no more advances have occurred toward more substituted metallacarborane chlorinated compounds [Cl₈–1]^–, [Cl₁₀–1]^–, and [Cl₁₂–1]^– are made with an easy and fast method. The key point of the reaction is the use of the protonated form of [Co(C₂B₉H₁₁)₂]^–, as a starting material, and the use of sulfuryl chloride, a less hazardous and easier to use chlorinating agent. In addition, we present a complete, spectroscopic, crystallog., and electrochem. characterization, together with a study of the influence of the chlorination position in the electrochem. properties. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Recommanded Product: Tetramethylammonium chloride).
