摘要
在对氨基苯磺酸催化作用下,以10-十一烯醛与乙二醇为原料合成了10-十一烯醛缩乙二醇。考察了醛醇摩尔配比、反应时间、催化剂用量及其重复使用性能等因素对反应的影响。较优反应条件为:10-十一烯醛用量0.1 mol,n(10-十一烯醛)∶n(乙二醇)=1∶1.2,催化剂用量0.5 g,环己烷带水剂12 mL,回流反应2.0 h,10-十一烯醛缩乙二醇的收率最高可达92.4%。
10-Undecenal glycol acetal was synthesized from 10-undecental and ethylene glycol using paminobenzene sulfonic acid as catalyst. The effects of the mole ratios of reactants, reaction time and amount of catalyst on the yield of 10-undecenal glycol acetal were investigated. The optimum reaction conditions were found as follows： 0. 1 mol 10-undecental, the molar ratio of 10-undecentat/ethylene glycol 1.0 ： 1.2, 0.5 g catalyst, 12 mL cyclohexane, reaction time 2.0 h. Under the optimum conditions, the yield reached 92.4%.
