Processes are provided for producing organchlorosilanes and dipodal silanes in which an organic halide or alkene or chloralkene is reacted with a hydridochlorosilane in the presence of a quarternary phosphonium salt catalyst by providing sufficient heat to effect a dehydrohalogenative coupling reaction and/or a hydrosilylation reaction and venting the reaction to control reaction pressure and to remove gaseous byproducts from the reaction. The processes are preferably continuous using a catalyst in fluid form at reaction pressures not exceeding about 600 psi. The reactions may be carried out substantially isothermally and/or isobarically, for example in a plug flow reactor or continuous stirred tank reactor. The processes may produce novel silylated compounds including 1,2-bis(trichlorosilyl)decane or 1,2-bis(trimethoxysilyl)decane.
提供了生产有机氯硅烷和双极硅烷的工艺,其中在四元磷盐催化剂的存在下,有机卤化物或烯烃或氯代烯烃与氯化硅氢反应,提供足够的热量以实现去卤素偶联反应和/或硅氢化反应,并通风以控制反应压力并从反应中去除气态副产物。该工艺最好是在不超过约600 psi的反应压力下使用流体形式的催化剂进行连续反应。该反应可以在基本等温和/或等压条件下进行,例如在塞流反应器或连续搅拌槽反应器中。该工艺可以生产新颖的硅化合物,包括1,2-双(三氯硅基)癸烷或1,2-双(三甲氧基硅基)癸烷。
