摘要: 从降低生物柴油的成本和综合利用副产物甘油的角度出发,利用其副产物75%粗甘油替代纯甘油合成单硬脂酸甘油酯;用乙醇替代苯萃取重结晶;以中心组合设计试验得出最佳的条件。研究表明,最佳工艺条件为:物料比2.8,反应时间1.8h,反应温度240℃。得到的含量为97.97%的高纯度单硬脂酸甘油酯,可作为食品添加剂。

Abstract: For decreasing the cost of biodiesel and utilizing the by-product glycerol, as by-product 75% raw glycerol instead of pure glycerol monostearin was synthesized, extracted and recrystalized with glycerol instead of benzene. Central combination design method was applied to design the test. The optimal conditions: the mole ratio 2.8, the reaction temperature 240 ℃ and the reaction time 1.8 h. After leaching and riming with ethanol, monostearate content was 97.97%, which can be used as food additive.
