Abstract : Tetraethoxysilane was thermally decomposed in apparatus similar to that used by the electronics industry to deposit silicon dioxide. A study of the decomposition reaction was made from the aspect of collected products. The reaction products were collected and analyzed by gas-liquid chromatography, and a mixture of acetaldehyde, ethane, ethanol, and ethylene was found. Comparison with the thermal decomposition products of diethyl ether suggests possible mechanisms for the decomposition of tetraethoxysilane. (Author)
