专利号:US-2023192731-A1 优先权日:2020-05-29 标 题 :Process for the stepwise synthesis of silahydrocarbons 发明人:AUNER NORBERT; STURM ALEXANDER G; SANTOWSKI TOBIAS; FELDER THORSTEN 权利人:MOMENTIVE PERFORMANCE MAT INC 摘要:The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCl reagent, or by selective chlorination of hydridosilanes with SiCl 4 , at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.
专利号:US-5973095-A 优先权日:1997-04-21 标题 :Synthesis of hydrogensilsesquioxane and organohydridosiloxane resins 发明人:HACKER NIGEL P; KRAJEWSKI TODD; LEFFERTS SCOTT 权利人:ALLIED SIGNAL INC 摘要:Novel processes for preparing hydridosiloxane and organohydridosiloxane resins are disclosed. The processes of the invention broadly provide for the steps of contacting a silane monomer with a solid state catalyst in the presence of a reaction mixture that includes a nonpolar, e.g., hydrocarbon, solvent, and a polar solvent, e.g., alcohol and water. The process is conducted under conditions effective to catalytically convert said silane monomer into hydridosiloxanes and organohydridosiloxanes. Recovery of the products is advantageously aided by the ease of separating the solid state catalyst from the reaction mixture. Hydridosiloxanes and organohydridosiloxanes resins produced by the processes of the invention are also provided.

The processes of the invention broadly provide for the steps of contacting a silane monomer with a phase transfer catalyst in the presence of a reaction mixture that includes a nonpolar, e.g., hydrocarbon, solvent, and a polar solvent, e.g., alcohol and water. The process is conducted under conditions effective to catalytically convert said silane monomer into hydridosiloxane and organohydridosiloxane resins. Recovery of the products is advantageously aided by the ease of separating the phase transfer catalyst from the dual phase reaction mixture by separating the immiscible polar solvent carrying the catalyst from the nonpolar solvent that carries the product. Hydridosiloxane and organohydridosiloxane resins produced by the processes of the invention are also provided.
