Study on the cohydrolysis and condensation reactions of methylphenyldichlorosilane with phenyltrichlorosilane

研究了甲基苯基二氯硅烷与苯基三氯硅烷的共水解缩合反应,探讨了甲基苯基二氯硅烷含量、反应温度、水的用量及反应时间对水解缩聚反应的影响,确定了最佳工艺。采用红外、核磁等手段对水解缩聚产物进行了结构表征。

The cohydrolysis and condensation reactions of methylphenyldichlorosilane with phenyltrichlorosilane were studied. The influencing factors of reactions such as the compositions of reactant, reaction temperature, reaction time, and molar ratio of H20 with Si-C1 bonds were investigated, and the optimal reaction conditions were determined. The structures of reaction product were characterized by FT-IR and ^1 H-NMR.^29 Si-NMR.
