本法以蔗糖、棉籽油为原料 .首先使苛性钾与脂肪酸乙酯反应生成部分中性皂作为乳化剂 ,并加入一定量的蔗糖 ,使蔗糖和脂肪酸乙酯在较低温度下既可达到相溶状态 ,进而在均相下发生酯交换反应合成蔗糖酯 .适宜的反应条件为 :蔗糖∶脂肪酸乙酯 =1∶ 0 .8;皂用量 1 5 % ;催化剂用量 2 % ;反应温度 1 3 5℃ ;反应时间 1 65 min;压力≤ 666Pa;所得产品 HLB值高于 1 4 The method takes sucrose and cottonseed oil as raw materials, and firstly makes caustic potash react with fatty acid ethyl ester to form part of neutral soap as an emulsifier, and adds a certain amount of sucrose so that sucrose and fatty acid ethyl ester can reach phase Sucrose and fatty acid ethyl ester = 1: 0. 8; the amount of soap is 15%; the amount of catalyst is 2%; the reaction temperature is 1 3 5 ℃; reaction time 1 65 min; pressure ≤ 666 Pa; the HLB value of the product is higher than 1 4
