摘要
研究了用POCl3 交联木薯淀粉的性质。结果表明,反应条件对产物交联度有不同程度的影响,其中用量和温度的影响最大。木薯原淀粉在碱性条件下,用POCl3 处理,主要产品为淀粉磷酸二酯。
This article studied on the properties of tapioca starch dealed with POCl_3(0.002%~0.01%) at five levels. The results showed that reaction condition, especially of dose and temperature, had different effects on the cross-linking degree of the products. The main product was phosphodieste when tapioca starch was prepared by POCl_3 under alkaline condition.
