摘要
采用水溶剂法合成蔗糖单硬脂酸酯适宜的反应条件为 :蔗糖与硬脂酸单甘酯摩尔比为 3∶ 1、乳化剂用量5%、催化剂用量 5%、水用量 10 %、反应温度 150℃、反应时间 4 h、压力 0 .0 7～ 0 .14 Pa。重量收率 111.5% (以硬脂酸单甘酯计 )
The monostearic sucrose ester was synthesized with water solvent, optimal condition sucrose: fatty acid glyceride = 3∶1(mole Ratio); emulsifying agent 5%, catalyst 5%,water 10% (based on the weight of main reactants); reation time 4 h, temperature 150 ℃, vacuum 0.07～0.14 Pa. 111.5% product was obtained(basis in the weight of fatty acid glyceride)
