| 摘 要： | 以糯玉米淀粉为原料,先对其氧化处理,然后用辛烯基琥珀酸酐对氧化淀粉进行酯化.在单因素基础上选取影响酯化取代度明显的四个因素(pH值、反应温度、淀粉乳浓度、反应时间)在酸酐加入量为3%及酸酐用乙醇稀释5倍的前提下进行响应面设计,得出了最优条件:pH值为8.4,反应温度为36%,淀粉乳质量分数为40%,反应时间为3.5 h,酯化剂用量3%(占淀粉干基比),此时制备产品的取代度可达0.0196.

| Abstract: | Glutinous corn starch was oxidized at first and then esterified with octenyl succinic anhydride.The technological parameters for preparing octenyl succinate anhydrate(OSA) modified starch in terms of pH,temperature,starch slurry and reaction time were optimized using a response surface design under a condition of 3% OSA in a medium of alcohol.The optimum conditions were obtained as follows: pH 8.5,reaction temperature 35,the original concentration of starch slurry 40% and reaction time 3 h.Under these condi... |
