摘要
研究了合成蔗糖月桂酸酯中采用相转移催化的基本原理和方法，考察反应时间，原料的不同配比和催化剂用量对蔗糖月桂酸酯产率的影响，得出反应时间为４．５ｈ，原料配比为１∶１（摩尔数），催化剂用量为月桂酸甲酯摩尔数的８％时，其蔗糖月桂酸酯产率８６．５％～９１．２％，产物经纯化后测定，蔗糖单月桂酸酯按每克产品含蔗糖月桂酸单酯的摩尔数与理论计算的摩尔数之比为０．９７２５∶１．００００．
In relation to the synthesis of sucrose laurate by phase transfer catalysis (PTC),the basic principle and the method of PTC are studied;and the effects of reaction time and raw maerial proportioning and catalyst consumption on sucrose laurate output rate in weight are inspected. A sucrose laurate output rate of 86.5%～91.2% is obtained under such conditions as a reaction time of 4. 5 hours and a raw material proportioning of 1:1 mole number and a catalyst consumption of 8% methyl laurate mole number. The sucrose monolaurate content of purified product is determined to be 97. 25%.
