摘要: 以天然大豆油和玉米淀粉为原料制备了具有两亲性的新型表面活性剂——淀粉脂肪酸酯。利用响应面软件设计试验,并建立数学模型,在分析各个因素的显著性和交互作用后,得出酯化反应的最佳条件:反应时间11.6h,反应温度56.3℃,催化剂1.14%,物料比(淀粉:脂肪酸甲酯)1:1.4(W/W)。所得产品取代度是0.10683。

Abstract: A new kind of surfactant, i.e. starch fatty acid esters, was prepared with nature soybean oil and starch as raw materials in this paper. The reaction conditions were studied with response surface methodology design. A reaction model and the optimum conditions were got as the results. The optimum synthesis conditions were as follows: the reaction time of 11.6 h, reaction temperature of 56.3 ℃, catalyst of 1.14% and ratio of starch to fatty acid methyl esters of 1:14(W/W). The substitute degree of product was up to 0.10683.
