摘要:
A one-step process for the preparation of organosilicon intermediates. The organosilicon intermediates comprise a group which includes such intermediates as 1,4-bis(dimethylsilyl)benzene, 1,4-bis(dimethylchlorosilyl)benzene, and their derivatives. The process comprises: combining a dihalobenzene with magnesium metal in a co-solvent mixture of an ether and an organic solvent and reacting them with an organosilicon compound of the general formula, R2bHcSiXd. The resulting mixture is allowed to react to completion. The resulting mixture is passed through a filtration device. The liquid, now free of solid magnesium halide, is subjected to a separation technique to recover the subject organosilicon intermediates and their derivatives.

Process for the production of alkoxysilanes of the formula HSi(OR)3, where R is an alkyl group containing 1 to 6 carbon atoms, and/or alkyl orthosilicates of the formula Si(OR)4, where R is an alkyl group containing 1 to 6 carbon atoms. In a preferred embodiment, the process comprises reacting silicon metal with an alcohol in a suitable solvent in the presence of a cupric bis(diorganophosphate) catalyst. A polymeric form of ethyl orthosilicate, a by-product of the reaction, is the preferred solvent. The production of triethoxysilane and tetraethyl orthosilicate is preferred, with triethoxysilane being particularly preferred.
摘要:
Abstract Organosilicon compounds having the formula I and/or II 1 wherein R1 is a mixture and the proportion of one component of the mixture is 10 to 50 mol %, are produced by reacting silanes having the formula III 2 with mixtures of alcohols having the general formula R1nullOH, with elimination of RnullOH, and RnullOH is continuously separated off from the reaction mixture by distillation. The organosilicon compounds can be used in rubber compounds.
