A silahydrocarbon functional fliud comprising a mixture of silahydrocarbons of the formula RSiR'3, wherein the R' radicals may be alike or different, is prepared by a three step process. In the first step in a preferred embodiment, sodium, aluminum, hydrogen, and olefin (corresponding to the radical R') are reacted in the presence of a triorganoaluminum catalyst. In a second step, fresh catalyst is added and reaction is continued. In a third step, the product of the second step is reacted with a trihaloalkylsilane to produce the RSiR'3 product. Such a product satisfied the U.S. Air Force specification for silahydrocarbon base stock. |
