摘要
以淀粉为原料,经环氧氯丙烷交联,制备低交联度的醚化淀粉。并测定不同交联度的淀粉的粘度峰值、交联度、溶胀性及析水率,确定制备交联淀粉的最佳工艺条件为:交联pH10,交联剂用量0.3%,交联时间3h,交联温度25℃。
This article is on the study of synthesis of modified starch with eplchlodhydrin. The viscosity properties, cross-linking degree and swelling capacity were determined at different conditions. It showed that the optimal conditions for making high viscosity starch were 0.3 % eplchlorlhydrin, 2.5h for cross-linking reaction, cross- linking pH 10, temperature 25 ℃.
