| 摘 要： | 以玉米淀粉为原料,以3-氯-2羟丙基三甲基氯化铵(CHPTMA)为醚化剂,以NaOH为催化剂的条件下,半干法制备了低取代度阳离子淀粉。确定了半干法制备低取代度阳离子淀粉的工艺路线,研究了各反应因素对阳离子淀粉反应效率的影响,并以反应效率为指标,利用二次通用旋转试验建立了相应的回归方程,确定了最佳工艺参数为:NaOH与醚化剂的摩尔比1.85∶1,体系含水量20.49%,反应温度60.65℃,反应时间4.49h,最佳条件下制备的阳离子淀粉反应效率可达到89.48%,取代度为0.0335。

| Abstract: | The cationic starch with low degree of substitution was half-dry prepared from corn starch, CHPTMA and NaOH.The technology process and the effect of four factors have been studied.Using quad- ratic general rotary experiment design,the regression equation of the degree of substitution with factors was established.The optimum technology conditions were confirmed as followings:the ratio of CHPTMA and NaOH was 1.85,the water content was 20.49%,the reaction temperature was at 55℃,the reaction time was 4 hours,the reaction efficiency was up to 89.48% ,the degree of substitution was 0.0335. |
