一、概述硅有机化合物的分析,通常是采用定氯等化学法来进行测定。由于直接合成法制得的甲基氯硅烷混合物,其组分极为复杂,包括:HCl(沸点-84℃),MeCl(沸点-23.7℃),Me_4Si(沸点26.5℃),HSiCl_3(沸点31.8℃),Me_2SiHCl(沸点36℃),MeHSiCl_2(沸点41.0℃),Me_3SiCl(沸点57.3℃),SiCl_4(沸点57.7℃),Me_3SiCl_3(沸点65.7℃),Me_2SiCl_2(沸点70.0℃)等,沸点又很接近,因此,一般应用精密分镏后测定比重的结果,误差很大,且操作麻烦。也有用
First, an overview of the analysis of silicon organic compounds, chlorine determination is usually used to determine the chemical method. The composition of the methylchlorosilane mixture obtained by the direct synthesis method is extremely complicated and includes components such as HCl (boiling point -84 ° C), MeCl (boiling point -23.7 ° C), Me_4Si (boiling point 26.5 ° C), HSiCl_3 (boiling point 31.8 ° C) Me boiling point of 41.0 ℃, Me 3 SiCl boiling point of 57.3 ℃, SiCl 4 boiling point of 57.7 ℃, Me 3 SiCl 3 boiling point of 65.7 ℃, Me 2 SiCl 2 boiling point of 70.0 ℃, and so on. Therefore, The general application of precision after the determination of the proportion of the results, the error is large, and the operation is cumbersome. Also useful
