Reaction of tetraethoxysilane with the azeotropic mixture Me3SiCl-SiCl4 in the presence of certain cyclic (tetrahydrofuran, dioxane) and acyclic (diethyl ether) ethers, ethanol, or dimethylformamide was studied with the aim of SiMe3Cl recovery.

Tetraalkoxysilanes were treated with Amberlyst 15 cation-exchange resin in hexamethyldisiloxane at 40 deg C in order to substitute the trimethylsilyl group for the alkyl group in a tetraalkoxysilane partially.Tetramethoxy-, ethoxy-, propoxy-, and butoxysilanes were used for the experiments.After the treatment, SiO4R(4-n)Xn (1 /= n /= 4, R = CH3, C2H5, n-C3H7, and n-C4H9, X = Si(CH3)3) were detected by gas chromatography-mass spectrometry.The degree of trimethylsilylation of tetraalkoxysilane changed with the molar ratio of hexamethyldisiloxane to tetraalkoxysilane and quantities of the reaction products in the system depended mainly on the ratio.
