Abstract
An improved process for producing hexamethyldisilane by reacting ether solutions of methyl Grignard with a crude mixture of chloromethyl disilanes, the improvement which comprises obtaining higher yields and simplified purification of HMDS by the use of a mixed solvent system composed of tetrahydrofuran and the diethyl ether of tetraethylene glycol.
