【摘要】 以硬脂酸甲酯与甘油为原料,研究了以硅酸钠为催化剂制备甘油二酯的最佳工艺条件。结果表明,通过正交试验确定制备甘二酯的最佳工艺参数为:硬脂酸甲酯与甘油的摩尔比2∶1、反应温度220℃、反应时间2.5h、硅酸钠的添加量为硬脂酸甲酯质量的0.5%,在此条件下进行反应,测得反应产物中甘二酯的质量分数为49.70%。更多还原

【Abstract】 The optimum technological conditions for preparing Diacylglycerol(DG)from Methyl stearate and Glycerinx with Sodium metasilicate as catalyst were studied.As seen from the results,the optimum technological parameters for preparing Diacylglycerol were showed as follows:mole ratio of Methyl stearate to Glycerinx 2:1,reaction temperature 220℃, reaction time 2.5h,additive amount of Sodium metasilicate 0.5%(based on the weight of Methyl stearate).Under these reaction conditions,the mass fraction of DG in reaction product was 49.70%.更多还原
