部分水解的聚丙烯酰胺的胺甲基化改性及其在制糖应用研究

Study on the modification of aminomethylation of partially hydrolyzed PAM and Its application in sugar manufacture

对部分水解的聚丙烯酰胺 (PAM)的胺甲基化反应进行分析 .通过正交实验 ,选出胺甲基化反应的最优条件 .与未改性的 PAM比较 ,发现改性的 PAM能提高沉降速度 。

The reaction of aminomethylation of partially hydrolyzed PAM was analysed. The optimum condition of the modification of aminomethylation was obtained by orthogonal experiment. Compared with the unmodified PAM, it is found that the modified PAM can increase the settling rate, reduce the colour and turbidity of the sugar juice.
