Abstract
Mixtures of silahydrocarbons which comprise a product RSiR'.sub.3, wherein R is an alkyl of 1-4 carbons, and R' is an alkyl of 8-14 carbons are produced by reacting a silicon tetrahalide, SiX.sub.4, a trialkylaluminum, R.sub.3 Al, and an alkali metal aluminate NaAlR'.sub.4. An alkali metal salt increases the relative amount of RSiR'.sub.3 in the product. The trialkylaluminum can be replaced with an olefin or with an organoaluminum sesquihalide. The products are useful as functional fluids.
