| 摘要: |
| 本文对二甲苯溶剂中MeSiHCl2和甲醇的反应产物Me(OMe)2SiH 及MeSi(OMe)3作了红外和核磁共振分析, 结果表明: 以红外谱图中Si-H 和苯环吸收带作为含量分析谱带, 采用比例法, 借助工作曲线, 可确定反应产物的含量。亦可以通过对各组分处于不同化学位移下质子的核磁共振分析, 采用归一化法, 经过换算测定反应产物混合液中各组份含量。两种测定方法均简便快捷, 并对两法的测定结果作了分析比较。 |

| Abstract: |
| In this paper, the alcoholysis products synthesized by MeSiHCl2 and MeOH in xylene are examined by IR and 1H-NMR. The results indicated that the concentration of each composition can be calculated using the Si-H bond and phenyl group absorption peak as spectrum-band of quantitative analysis through the calibration curve and the scaling method in the IR analytical means, and also it can be established using the normalization method through the analysis of the different chemical shift parton H and a series of quantitative analytic calculations in 1H-NMR. Both methods are simple and rapid. The results of the two methods are compared. |
