阳离子松香施胶剂制备中的酯化反应

The esterification reaction of synthesis of constructing the glue pharmaceutical of rosin of postive ion

本文对制备阳离子松香中性施胶剂中的酯化过程进行了初步的研究。本文主要说明以松香为原料,加热熔融后加入甘油使其脱水酯化,通过改变反应温度、改变催化剂用量以及改变反应物配比,来确定松香酯化反应的最佳条件。

In this paper, study the esterification of synthesis of constructing the glue pharmaceutical of opstive ion. Rosin as mail raw materials ,after melting ,the rosin is maixed with glycerine and is esterificated.In order to confirm the optimum condition of the esterification of rosin.Some ways such as changing temperature,controling the catalyst consumption and changing the matching of reactant are adopted.
