Flash point (FP) is the primary property to classify flammable liquids to assess their fire and explosion hazards. Due to technol. advancement in discovering or synthesizing new compounds, there is often a significant gap between the demand for such data and their availability. Reliable methods to estimate the FP of a compound are indispensable. This work used a quant. structure property relationship study to predict the FP of organosilicon compounds To establish and validate proposed models, a dataset of 230 organosilicon compounds was collected and divided into a training set of 184 compounds and a testing set of 46 compounds A step-wise regression method selected the required mol. descriptors to predict organosilicon compound FP from 1538 mol. descriptors. Depending on the p-value to accept a descriptor to enter the model, models with different number of descriptors were obtained. Thus, 13- and 6-descriptor models were obtained with resp. p-values of 5 × 10^-4 and 1 × 10^-5. The 6-descriptor model fit the training data with R² = 0.8981; it predicted test data with Q² = 0.8533. The 13-descriptor model fit the training data with R² = 0.9293; it predicted test data with Q² = 0.9245. Average predictive errors were <5% for both proposed models and they are useful for many practical applications since they used only mol. structure-based calculated descriptors.

Shao, Dongyun published the artcilePreparation of polycarboxylic acid-functionalized silica supported Pt catalysts and their applications in alkene hydrosilylation, HPLC of Formula: 14799-94-1, the publication is RSC Advances (2018), 8(36), 20379-20393, database is CAplus and MEDLINE.

A series of novel immobilized platinum catalysts was prepared by loading Pt onto silica particles modified with polycarboxylic acid groups such as diethylenetriaminepentaacetic acid (DTPA), nitrilotriacetic acid (NTA) and succinic acid (SA). The three modified heterogeneous Pt catalysts were characterized using IR spectroscopy (IR), transmission electron microscopy (TEM), XPS, energy dispersive X-ray spectroscopy (EDS) and at. absorption spectroscopy (AAS). The residual H₂PtCl₆ solutions were characterized using UV spectroscopy (UV). The polycarboxylic acid-functionalized silica supported Pt catalysts were used to catalyze alkene hydrosilylation and 1-hexene was chosen as a model alkene. The data indicated that the catalytic performance was strongly dependent on the properties of the polycarboxylic acid group bonded to the silica particles. Among them, DTPA-functionalized silica supported Pt (SiO₂-DTPA-Pt) showed the best catalytic activity and reusability. Furthermore, some hydrosilylation reactions between other linear alkenes (1-heptene, 1-octene, 1-decene, 1-do-decene, 1-tetra-decene, 1-hexa-decene, 1-octa-decene, styrene or cis-hex-2-ene), or ring type alkenes (norbornene) with methyldichlorosilane could be catalyzed in the presence of these three Pt catalysts. Their high activities were more than 90%, and their selectivities were more than 99%, which were apparently better than homogeneous Pt catalysts. In addition, reactions with cyclohexene were also successfully catalyzed by the Pt catalysts. These results indicate that the polycarboxylic acid-functionalized silica gel supported Pt catalysts have potential value in industrial hydrosilylation reactions.

A smart design of transition metal nanocatalyst can efficiently improve its catalytic activity and use value. In this work, platinum (Pt) was successfully anchored to silica gel with phenylboronic acid group first time and formed nanoparticles (0.5-5 nm) which afforded a highly active supported catalyst for the hydrosilylation of olefins. The turnover number and regioselectivity in the reaction of methyldichlorosilane and 1-octene using 0.00000004 mol of the immobilized Pt catalyst approached 1,321,317 and 99% over 12 h. The corresponding hydrosilylation products in excellent yields and regioselectivities were obtained when we employed a broad range of terminal aliphatic olefins and methyldichlorosilane as substrates. The fully immobilized Pt nanoparticles could be recycled at least 10 runs without any obvious loss in catalytic activity.

Li, Laiming published the artcilePreparation, characterization and evaluation of a series of heterogeneous platinum catalysts immobilized on magnetic silica with different acid ligands, Application In Synthesis of 14799-94-1, the publication is Transition Metal Chemistry (Dordrecht, Netherlands) (2019), 44(8), 779-787, database is CAplus.

Platinum was immobilized on magnetic silica gel by means of boronic, nitric, carboxylic or sulfuric acid ligands to give four heterogeneous Pt nano-catalysts, designated as Fe₃O₄@SiO₂-BA@Pt, Fe₃O₄@SiO₂-NA@Pt, Fe₃O₄@SiO₂-CA@Pt and Fe₃O₄@SiO₂-SA@Pt, resp. Particles of these mono-dispersible Pt catalysts were 10-20 nm in size and could be separated for recycling by means of a magnet. Fe₃O₄@SiO₂-BA@Pt (0.174 mmol/g Pt) showed the best catalytic activity and selectivity, which were better than Speier’s catalyst. Its turnover numbers were up to 1.7 X 10⁶ and 1.1 X 10⁶ for hydrosilylation of 1-hexene or styrene, resp. This material could also catalyze the hydrosilylation of a broad range of alkenes and alkynes as substrates and methyldichlorosilane or triethoxysilane as silanes. Similar yields of 1-hexyl-methyldichlorosilane at the first and eighth runs (96.5% and 95.2%, resp.), together with a final Pt content of 0.171 mmol/g indicated the outstanding stability of Fe₃O₄@SiO₂-BA@Pt under the catalytic reaction conditions.

Li, Futing published the artcilePreparation of efficient and environment-friendly silica-supported EDTA platinum catalyst and its applications in hydrosilylation of olefins and methyldichlorosilane, HPLC of Formula: 14799-94-1, the publication is Journal of Molecular Catalysis A: Chemical (2016), 254-263, database is CAplus.

A novel catalyst by preparing silica supported EDTA (EDTA) platinum complex was developed. The preparation conditions, such as heating temperature and solvent types, were optimized. The catalyst was phosphine-free and sulfur-free which was characterized by IR spectroscopy (IR), energy dispersive X-ray spectrometer (EDS), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), XPS, UV spectroscopy (UV) and at. absorption spectroscopy (AAS). Its catalytic activity was evaluated by catalyzing solventless hydrosilylation reactions. In the hydrosilylation reaction between 1-hexene and methyldichlorosilane, the new catalyst showed a higher catalytic activity than that provided by Speier’s catalyst. Moreover, the new catalyst could be reused for 12 times without obvious loss of catalytic activity. To confirm its practical feasibility, catalyzing the hydrosilylation reaction between 1-octene and methyldichlorosilane was performed. Our results indicated that the new catalyst can efficiently catalyze the hydrosilylation reaction.

Vinyltriethoxysilane-platinum complex (I) has been prepared from vinyltriethoxysilane and chloroplatinic acid in the presence of anhydrous Na₂CO₃ and identified by IR measurement. Complex I supported on SiO₂ or self-polymerized gives polyvinyl siloxane-platinum complexes II and III resp. The complexes are highly active for hydrosilylation of unsaturated compounds, e.g. for the addition reaction of hexene-1 and methyldiethoxysilane, the conversion is 95% at 80 ° for 10 min or at 25 ° for 3 h in the presence of III. The addition rate of hydrosilicones to various unsaturated compounds catalyzed by these polymer catalyst is dependent on the mol. size and polarity of the reactant and the substituent on the double bond. The order of reaction rate is MeSiH(OEt)₂ > HSi(OEt)₃ > HSiCl₃ > MeSiHCl₂ and hexene-1 > octene-1 > allyl glycidyl ether > styrene > Et acrylate > Me methacrylate > α-methylstyrene. The polymer catalysts are stable and can be easily recovered and reused for several times without appreciable loss of activity.

HSiCl₃ adds with ease to olefinic double bonds in the presence of peroxides or ultraviolet light; the reaction appears to proceed exclusively by the addition of the SiH bond. In general, 0.5 or 0.75 mole olefin was used with 1 mole of the chlorosilane and 0.013-0.026 mole of peroxide (30% Ac₂O₂ in o-C₆H₄(CO₂Me)₂ used unless otherwise indicated); this mixture was heated 4-24 hrs. at 70-100°. 1-Pentene and HSiCl₃ give 73% AmSiCl₃, b. 166-9°, and MeHSiCl₂ gives 37% pentylmethyldichlorosilane, b. 164-8°. 2-Pentene and MeHSiCl₂ give 71% 2-pentylmethyldichlorosilane, b₁₀₀ 100°.

Jung, Sung-Hyun published the artcilePalladium-Catalyzed Direct Synthesis, Photophysical Properties, and Tunable Electroluminescence of Novel Silicon-Based Alternating Copolymers, Application In Synthesis of 14799-94-1, the publication is Macromolecules (2000), 33(25), 9277-9288, database is CAplus.

A new class of silicon-based alternating copolymers with a uniform π-conjugated segment regulated by organosilicon units was synthesized using the Heck reaction between distyrylsilane monomers and appropriate arylene dibromides. The incorporation of organosilicon units with the aromatic or aliphatic groups on the silicon atoms into π-conjugated systems improved their processability and interrupted the π-conjugation length. They could be spin-cast onto various substrates to give highly transparent homogeneous thin films. Their glass transition temperatures were in the range 94-127 °C. They show strong absorption bands around 356-416 nm, which corresponds to the π-π* transition of the conjugated segments. The maximum photoluminescence appeared around 440-526 nm in the blue or green emission region. Their optical properties depend on the arylene dibromides in the Heck reaction. The single-layered light-emitting diode of an Al/SiPhPPV or SiHMPPV/ITO glass exhibits a threshold voltage of 10-12 V from the I-V curve. The electroluminescence (EL) of the SiPhPPV or SiHMPPV gives an emissive peak at 450 nm. Furthermore, the multilayered light-emitting diodes of an Al/LiAl/SiPhPVK/PANI/ITO glass and an Al/LiAl/SiPhFPV or SiHMFPV/ITO glass shows a threshold voltage of 6-12 V. The EL device based on SiPhPVK exhibits the blue emissive color at 467 nm, when an operating voltage of 7 V was applied. When an operating voltage of 11 V was applied, however, the EL device emits a white color. The EL spectra of the SiPhFPV and SiHMFPV polymers, obtained at an applied voltage of 12 V, show two strong peaks in the blue emissive region as well as in the green region.
