Abstract
This invention relates to a process for preparing tetrahydrocarbylsilane in high yield, comprising: a) forming a reaction mass from molten metal and trihydrocarbylaluminum, in an hydrocarbon solvent under an inert gas atmosphere; b) maintaining the reaction mass at a temperature in the range of from about 100.degree. to about 130.degree. C. for a period of time sufficient to form sodium tetrahydrocarbylaluminate; c) contacting the sodium tetrahydrocarbylaluminate with organotrihalosilane; and d) heating the contacted tetrahydrocarbylaluminate and organotrihalosilane to a temperature and for a period of time sufficient to form the tetrahydrocarbylsilane, wherein the tetrahydrocarbylaluminate and tetrahydrocarbylsilane are formed at a pressure of less than about 3000 KPa and wherein the hydrocarbyl group of the tetrahydrocarbyl silane is one or a mixture of hydrocarbyl groups having less than about 8 carbon atoms each.
