摘要
以苯甲醛和乙二醇为原料,采用氨基磺酸作催化剂合成苯甲醛乙二醇缩醛,考察了影响反应的主要因素。结果表明,反应的优化条件为:n(苯甲醛)∶n(乙二醇)∶n(氨基磺酸)=1∶2.0∶0.082、带水剂环己烷10 mL、反应时间75 min,此时缩醛产率可达93.07%。
Benzaldehyde glycol acetal was synthesized with benzaldehyde and glycol as raw materials and sulfaminic acid as catalyst.The main factors influencing on the reaction were investigated.Experimental results indicated that the optimum conditions of esterification reaction were as follows: the molar ratio of benzaldehyde and glycol and sulfaminic acid 1∶2.0∶0.082,water-carrying agent of cyclohexane 10 mL,the reaction time 75 min,and the acetal yield was up to 93.07%.
