摘    要:通过催化合成苯甲醛缩乙二醇和丁醛缩乙二醇的反应,考察了3种含硅三烃基锡化合物和2种含硅二烃基锡化合物在缩醛反应中的催化活性,并以丁醛与乙二醇的反应为例,讨论了催化剂用量、反应时间和溶剂等因素对反应的影响。实验结果表明,5种含硅有机锡化合物在缩醛反应中均表现出一定的催化活性;在丁醛与乙二醇的反应中,当n(丁醛):n(乙二醇)=1:1,三(三甲基硅基)亚甲基]氯化锡用量为反应物料质量分数的1.8%,环己烷为带水剂,反应时间5 h时,丁醛缩乙二醇的收率可以达到88.6%。

关 键 词:含硅有机锡化合物  催化  缩醛反应

Abstract:The catalytic properties of silicon-containing trihydroxyltin and dihydroxyltin compounds were studied in the syntheses of benzaldehyde glycol acetal and butyraldehyde glycol acetal.The fac- tors influencing the reaction,such as catalyst dosage,reaction time and types of solvents,were inves- tigated based on the reaction of butyraldehyde and glycol.The results showed that all the five organo- tin compounds possessed certain catalytic activities.In the reaction of butyraldehyde and glycol,when n(butyraldehyde):n(glycol)=1:1,the amount of tri(trimethylsilyl)methyl]tinchloride as cat- alyst was 1.8% based on the mass of the reactants,cyclohexane as water carrying agent,and reaction time 5 h,the yield of butyraldehyde glycol acetal reached 88.6%.
Keywords:silicon-containing organotin compounds  catalysis  acetalization
