摘要
以硬脂酸和乙二醇为原料,酸性离子液体为催化剂,制备了乙二醇硬脂酸酯。结果表明,离子液体催化活性很高,在醇酸摩尔比1 1,反应温度120℃,反应时间3h的条件下,酯化转化率可达91.65%,且离子液体稳定,可循环使用。
Glycol stearate was prepared by using esterification of glycol with stearic acid in the presence of catalyst acidic inoic liquid.Under esterification conditions n(glycol) : n(stearicacid) =1 : 1, temperaturel20℃ and time 3h and the yield may up to 91.65%. The ionic liquids were stable and could be reused.
