摘要
研究了在催化剂存在下低酯化度果胶与甲醇进行的甲酯化反应。选择适当的催化剂,控制不同的反应温度及反应时间,可以制备出不同酯化度(可高至80%)的果胶系列产品。
The methyl- esterification reaction of low -methoxyl pectin with methylalcohol by the presence of some catalysts was observed . The pectin having various degrees of methyl-esterification which are from the lower levels to about80% had been prepared by selecting the suitable catalysts,and controlling the reaction temperature and time .
