Abstract
Trimethylchlorosilane which contains methyltrichlorosilane and/or silicon tetrachloride as impurities is treated with a solution of water and an organic ether solvent miscible with both the water and the silanes, the amount of water being from 0,2 to 0,9 moles per atom of silicon-bonded chlorine in the impurities, and trimethylchlorosilane of greater purity is recovered, e.g. by distillation. The amount of impurities is such that there are 0,25 to 2,5 parts of trimethylchlorine per part of other chlorosilanes. The organic ether directs the hydrolysis to the methyltrichlorosilane and silicon tetrachloride. Specified ethers are dioxane -1,4 and 1,3, tetrahydrofuran and diethyl and dipropyl ethers. The amount of ether is preferably from 2 to 50 moles per mole of water.
