本研究报告了在相转移催化剂存在下,水玻璃与有机锡化合物反应,可以得到高粘性液体产物。考察了各种条件对反应的影响,结果表明:水相的pH在一定范围内反应才能进行;有机溶剂种类对产物分子量的大小有明显影响;相转移催化剂的效率与过去报道的水-苯体系的结论相一致。
This study reports that sodium silicate reacts with organotin compounds in the presence of a phase transfer catalyst to give highly viscous liquid products. The effects of various conditions on the reaction were investigated. The results showed that the pH of the aqueous phase reacted within a certain range. The type of organic solvent had a significant effect on the molecular weight of the product. The efficiency of the phase transfer catalyst was similar to that reported in the water-benzene system Consistent with the conclusion.
