摘要
将固体酸SO42-/ZrO2-Fe2O3用于催化L-乳酸和2-异亚丙基氨基氧基乙醇的酯化反应。确定了最佳反应条件:带水剂为甲苯,醇酸摩尔比为3.5:1,催化剂用量为L-乳酸质量的6%,反应时间为8 h,在此条件下酯化率可达62.5%。
Solid acid SO2-4/ZrO2-Fe2O3 was used as catalyst for the esterification of L-lactic acid and 2-[（isopropylidieneamino）oxy]ethanol.The optimum conditions of esterification was as follow： water-taken reagent was toluene,the molar ratio of alcohol to acid was 3.5：1,catalyst of dosage was 6%（mass of lactic acid）,reaction time was 8 h.Under the experimental conditions,the ratio of esterification was 62.5%.
