摘要: 1H-NMR系统的测定了不饱和酯类的氢硅加成产物、指认了1H-NMR各谱峰的归属。建立了分析加成产物中α-结构和-β结构百分比含量的全积分处理方法。对照化学分析方法,本方法具有快速、可靠和能跟踪化学反应体系结构组成的变化等优点。

Abstract: 1H-NMR technique was used to study systematically the additive products formed by the hydrosilation reactions of the unsaturated ester. The chemical shifts of 1H-NMR spectra of the additive products were assigned. We advanced the method to calculate the percentage of the α-and β-species in the additive products. In contrast with chemical analysis method, the advantages of this method are rapid accurate and capalle to follow the changes of the structure of the reaction system.
