Iodine or iodine monobromide was found to be an especially favorable catalyst for the study of the alcoholysis equilibria of dialkoxydimethylsilanes by gas chromatography. Iodine monobromide was employed to promote the reactions associated with tertiary alcohols, and iodine was used for the other reactions. Eight alcohols were allowed to react with diethoxydimethylsilane, and successive equilibrium constants, K 1 and K 2 were ...
