摘要
利用气相色谱和1H NMR核磁共振分析了六甲基二硅氧烷(MM)中三甲基硅醇的含量。配备氢火焰离子化检测器(FID)的气相色谱进行准确定量。结果表明:采用FID气相色谱测定样品中三甲基硅醇的含量为53.15%;采用TCD气相色谱检测样品中三甲基硅醇的含量为55.27%;核磁共振检测出三甲基硅醇的质量分数为51.59%。
The content of trimethylsilanol in hexamethyldisiloxane was analyzed by 1H NMR and gas chromatography with the hydrogen flame ionization detector（FID）.Result showed that FID GC determined the content of trimethylsilanol in the sample was 53.15%;TCD determined the content of trimethylsilanol in the sample was 55.27 %;the mass fraction of trimethylsilanol by 1H NMR was 51.59%.
