The silahydrocarbon product containing at least 75 weight percent of saturated silahydrocarbons with the remainder being unsaturated silahydrocarbons is produced by a process in which admixture comprising (A) at least one alpha-olefin containing from 2 to about 20 carbon atoms per molecule, and (B) at least one alkylsilane selected from the group consisting of (i) a dialkylsilane having the formula R--SiH.sub.2 --R.sub.1 (ii) a trialkylsilane having the formula ##STR1## and (iii) mixtures thereof, wherein R and R.sub.1, the same or different, each represent an alkyl radical of from one to 20 carbon atoms per molecule with a catalyst comprising a homogeneous rhodium-containing catalyst or a heterogeneous rhodium-containing catalyst in a halogen-free inert solvent, under hydrosilylation reaction conditions to produce a mixture containing saturated and unsaturated silane hydrocarbons useful as lubricants. The unsaturated silane hydrocarbons can be substituted with sulfur to provide improved lubricating characteristics.
含有至少75重量%饱和硅氢化合物的硅氢化合物产品是通过以下过程生产的:将混合物(A)至少包含每个分子中2到约20个碳原子的α-烯烃,和(B)至少包含以下组中选择的一种烷基硅烷混合:(i)具有R-SiH.sub.2-R.sub.1公式的二烷基硅烷,(ii)具有以下公式的三烷基硅烷##STR1##和(iii)其混合物,其中R和R.sub.1,相同或不同,分别表示每个分子中的一种含有1到20个碳原子的烷基基团,与含有均相或非均相含铑催化剂的卤素无溶剂,在氢硅烷化反应条件下产生含有饱和和不饱和硅氢烃的混合物,可用作润滑剂。不饱和硅氢烃可用硫代替,以提供改良的润滑特性。
