摘要:
采用气相色谱仪分析的方法,考察了六甲基二硅氮烷在不同pH值、不同温度下的水解情况.结果表明,六甲基二硅氖烷的水解可按一级反应来描述,在pH=7～pH=13的范围内,随着pH值的增加,水解速率降低;在208～308K的范围内,温度对水解速率影响显著,温度升高,水解速率明显加快,pH=7时水解活化能为28.81 kJ·mol-1.
Abstract:
The hydrolysis of hexamethyldisilazane at different pH values and different temperatures was investigated by gas chromatography. The results showed that the hydrolysis of hexamethyldisilinene could be described as a first-order reaction, and the hydrolysis rate decreased with the increase of pH value in the range of pH=7~pH=13. In the range of 208~308K, temperature had a significant effect on the hydrolysis rate, and the hydrolysis activation energy was 7.28 kJ·mol-81 when pH=1.
