The solute -solvent interaction between ionic liquids (ILs) and amino acids (AA) in aqueous media plays a significant role for the optimization of a number of important biotechnol. processes. L-Valine and L-Proline (two solute mols.) interact with an ionic liquid (Benzyltributylammonium chloride) in aqueous medium. Based on the different parameters such as apparent molar volume, viscosity B-coefficient, molar refraction, molar conductance at different temperatures and different concentrations from d., viscosity, refractive index, conductance measurements have been used to explain the mol. level interactions which was supported by NMR and UV-Vis studies. Using Masson equation, the exptl. slopes and the limiting apparent molar volumes are obtained which explain the solute-solute and solute-solvent interactions. Hepler’s technique and dB/dT values have been used to examine the structure-making and structure-breaking nature of the solutes in the solvents. Viscosity parameters, A and B obtained from Jones-Doles equation explained the solute-solute and solute-solvent interactions in the solution Lorentz-Lorenz equation has used to calculate the molar refraction. The specific conductance also explained the interaction properties. Further the findings have been supported by NMR study of the solutions and also considerable amount of theor. anal. has been done which was in good agreement with the exptl. result. The behavior of many other bio-mols. can be explained by considering amino acids as model and the mechanism has been extended to elucidate the behavior of other (biol.) systems. In our findings we were emphasized on the nature of solute-solvent interactions and the presence of structural effect on the solvent in solution to analyze the mol.-level interactions prevalent in the systems.

A highly effective method to synthesize dialkyl peroxides from alkyl hydroperoxides and alkyl bromides in a liquid-liquid-liquid system using tetraalkylammonium salts as phase-transfer catalysts is reported. This process was conducted in the presence of highly concentrated aqueous KOH solutions and cyclohexane as an organic solvent. In a liquid-liquid-liquid system, the phase-transfer catalyst forms an insoluble third-liquid phase between the organic and aqueous phases that enables the catalyst to be recycled multiple times. Dialkyl peroxides were obtained in high yields and with 100% selectivity.

Kwasny, Michael T. published the artcileThermodynamics of counterion release is critical for anion exchange membrane conductivity, HPLC of Formula: 23616-79-7, the publication is Journal of the American Chemical Society (2018), 140(25), 7961-7969, database is CAplus and MEDLINE.

As the field of anion exchange membranes (AEMs) employs an increasing variety of cations, a critical understanding of cation properties must be obtained, especially as they relate to membrane ion conductivity Here, to elucidate such properties, metal cation-based AEMs, featuring bis(norbornene) nickel, ruthenium, or cobalt complexes, were synthesized and characterized. In addition, isothermal titration calorimetry (ITC) was used to probe counterion exchange thermodn. in order to understand previously reported differences in conductivity The ion conductivity data reported here further demonstrated that nickel-complex cations had higher conductivity as compared to their ruthenium and cobalt counterparts. Surprisingly, bulk hydration number, ion concentration, ion exchange capacity, and activation energy were not sufficient to explain differences in conductivity, so the thermodn. of metal cation-counterion association were explored using ITC. Specifically, for the nickel cation as compared to the other two metal-based cations, a larger thermodn. driving force for chloride counterion release was observed, shown through a smaller ΔH_tot for counterion exchange, which indicated weaker cation-counterion association The use of ITC to study cation-counterion association was further exemplified by characterizing more traditional AEM cations, such as quaternary ammoniums and an imidazolium cation, which demonstrated small variances in their enthalpic response, but an overall ΔH_tot similar to that of the nickel-based cation. The cation hydration, rather than its hydration shell or the bulk hydration of the membrane, likely played the key role in determining the strength of the initial cation-counterion pair. This report identifies for the first time how ITC can be used to exptl. determine thermodn. quantities that are key parameters for understanding and predicting conductivity in AEMs.

Han, Shuaiyuan published the artcileReversible Complexation Mediated Living Radical Polymerization Using Tetraalkylammonium Chloride Catalysts, Category: chlorides-buliding-blocks, the publication is Macromolecular Rapid Communications, database is CAplus and MEDLINE.

The paper reports the first use of organic chloride salts as catalysts for reversible complexation mediated living radical polymerization Owing to the strong halogen-bond forming ability of Cl^–, the studied four tetraalkylammonium chloride catalysts (R₄N⁺Cl^–) successfully control the polymerizations of Me methacrylate, yielding polymers with low dispersities up to high monomer conversion (>90%). Benzyldodecyldimethylammonium chloride is further exploited to other methacrylates and yields low-dispersity block copolymers. Advantages of the chloride salt catalysts are wide monomer scope, good livingness, accessibility to block copolymers, and good solubility in organic media. Because of the good solubility, the use of the chloride salt catalysts can prevent agglomeration of catalysts on reactor walls in organic media, which is an industrially attractive feature. Among halide anions, chloride anion is the most abundant and least expensive halide anion, and therefore, the use of the chloride salt catalysts may lower the cost of the polymerization

Diblock copolymers of poly(methylene-b-ε-caprolactone) (PM-b-PCL) were synthesized in two steps: (a) polyhomologation, to obtain following oxidative cleavage of the carbon-boron, (PM, block1), an α-hydroxyl-ω-Me polymethylene (PMOH, CH3-[CH2]m-OH). Following transfer reaction to the ring-opening polymerization catalyst and (b) ring-opening polymerization (ROP) of ε-caprolactone (CL) (PCL, block2). In addition, a series of homopolymers derived from poly(ε-caprolactone) (PCL) oligoesters containing an end group of docosyl (CH3-[CH2]21- or C22) (C22-PCL) were obtained as a model to compare their phys. properties by DSC with those of PM-b-PCL. The oligomers derived from PM-b-PCL and C22-PCL were characterized by 1H and 13C NMR, AFM, DSC, GPC and MALDI-TOF. PM-b-PCL and C22-PCL were evaluated as compatibilizers for PE/PCL polymer blends. Identification and anal. of optimized blocks of PM-b-PCL by POM and SEM showed improved mixing of PE/PCL blends.

Deng, Yu published the artcileRecovery of rare earths in different media with novel dicarboxylate based ionic liquid and application to recycle SmCo magnets, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Hydrometallurgy (2022), 105844, database is CAplus.

Recovery and separation of rare earth elements was highly crucial but difficult. In this study, a well-designed new ionic liquid named as benzyltributylammonium decanedioate ([N_444Bn]₂[SA]) was developed to extract rare earths and sep. Sm(III) from the spent SmCo magnets in acetate medium for the first time. To exhibit the superiority of acetate medium, the extraction of Nd(III) and La(III) in three different media were comparatively investigated under different conditions, including equilibrium time, initial pH of aqueous solution, rare earth concentration, extractant concentration, salting-out agent concentration and extraction temperature The results revealed that the better extractabilities of La(III) were observed in acetate medium rather than those in chloride medium (i.e., 97.6% vs. 78.6%), which may be attributed to the low-hydrated nature of acetate ions. Importantly, the back-extraction experiments indicated that 91.4% Nd(III) can be stripped from [N_444Bn]₂[SA] by using 1.5 mol/L HOAc, revealing the outstanding reusability of ionic liquid in the industrial separation-stripping cycles. Furthermore, the ion association mechanism was proposed to describe the extraction behavior and confirmed by the slope anal. and FT-IR characterizations in three media. In terms of the SmCoCu mixture separation, the maximal separation factor of Sm(III)/Co(II) was calculated as 3078 in simulated solution Impressively, the recovery of Sm(III) from the actual SmCo magnets by our dicarboxylate-type ionic liquid was also successfully achieved with a recycling rate of 96.8% and a Sm(III)/Co(II) selectivity of 148, which exhibited the potential application in the separation of Sm(III) from the spent SmCo magnets.

Ortho-Selective carbene C-H insertion of unprotected phenols is achieved with di-Me diazomalonate under the catalysis of [Rh(COD)Cl]₂. After the C-H insertion, subsequent cyclization and electrophilic addition of another carbene mol. affords tris-carboxylate-substituted 2-benzofuranones as the final reaction products. The enantioselective variant has been developed with the use of chiral diene ligands. Mechanistic experiments indicate that a transient oxonium ylide directing group might be responsible for the regiocontrol at the C-H activation step.

Depending on the synthetic method, the heteroatom-doped hexagonal B nitride (h-BN) catalysts can have different configurational entropies possessing various at. short-range orderings or phase separations, leading to complex grain boundaries for catalytic reactions. Herein, several C and O co-doped h-BN (BCNO) catalysts with different at. orderings were synthesized from the ternary deep eutectic solvents (DES). The exptl. results indicated the low steric resistance DES induced high-entropy structures (HES) in the BCNO, which involved a high d. of grain boundaries. The HES was studied as a catalytic booster for the radical initiation of aerobic oxidative desulfurization (ODS) of diesel. As a result, the optimized BCNO catalyzed ODS process owned the shortest induction period, rendering the complete aerobic oxidation of refractory S compounds in 6 h.
