Abstract
A diorganodichlorosilane of greater purity is obtained from mixtures of such silane and an organotrichlorosilane in which the trichlorosilane comprises at most 20% by weight of the mixture by adding a solution of water and an ether miscible with both the water and silanes, the amount of water being substantially less than that required to hydrolyse the dichlorosilane and being from 0,5 to 2 moles per mole of the trichlorosilane, and recovering the dichlorosilane, e.g., by distillation. The ether, which effects a preferential hydrolysis of the trichlorosilane, is preferably in an amount of 2 to 50 moles per mole of water. Specified ethers are dioxane, tetrahydrofuran, diethyl ether and dipropyl ether. Reaction may be carried out at room temperatures or up to 150 DEG C. The organic radicals on the silanes may be alkyl, alicyclic, aryl, alkaryl, aralkyl and alkenyl, and they may be substituted, e.g., by halogen, cyano and amino groups. Specification 712,059 is referred to.
