摘要
本法以苛性钾与脂肪酸甲（乙）酯首先反应生成的部分中性皂作为乳化分散剂，使蔗糖和脂肪酸甲（乙）酯在熔融状态下直接发生酯交换反应合成蔗糖酯。适宜的反应条件为：蔗糖／硬脂酸甲酯／苛性钾／催化剂的摩尔比１：１～２：０．４～０．６：０．００３６；１３５～１４０℃、２０～５０ｍｍＨｇ负压下反应３～３，５ｈ。所得粗产物含蔗糖酯５５％，其中单酯６２％。
In this method KOH and fatty acid methyl (ethyl) ester firstly reacted andpartly changed into neutral soap as a emulsifying agent which makes the sugar andfatty acid methyl ester directly give rise to a ester exchange reaction and compose thesugar ester in the smelting state. The proper reacting conditions are: sugar/methylstearate /KOH/catalyst (mol ratio) being l: 1～2: 0.4～0.6: 0.0036; 135～140℃; 20～50mmHg; reacting duration 3～3.5h. The raw product contains SE 55% in whichMSE is 62%.
