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.
