以生物柴油和蔗糖为原料,在N2保护下采用无溶剂法合成蔗糖酯,以活性炭负载的碳酸钾为催化剂,确定了蔗糖酯合成技术的各项工艺条件:生物柴油与蔗糖的物质的量比为2∶1,在N2保护下,催化剂活性炭负载碳酸钾加入量为总物料量的6%,助溶剂硬脂酸钾加入量为15%,在135℃下反应3h,采用溶剂萃取法纯化粗产物,精制后的蔗糖酯产率以蔗糖记为86.4%。 Using biodiesel and sucrose as raw materials, sucrose esters were synthesized by solvent-free method under the protection of N2. The technological conditions for the synthesis of sucrose esters were determined on the basis of potassium carbonate supported on activated carbon: the amount ratio of biodiesel to sucrose Is 2: 1, under the protection of N2, the amount of potassium carbonate loaded on the catalyst is 6% of the total amount of the material, the amount of potassium stearate added is 15% and the reaction is carried out at 135 DEG C for 3 hours, and the crude product is purified by solvent extraction The yield of refined sucrose ester was 86.4% with sucrose.
