摘要
在缩合反应中,用载体固体碱作催化剂有如下优点:反应条件温和,催化反应活性高,选择性强,后处理简单,产率高且无机载体可再生重复使用.在实验中,用NaOH-Al2O3催化苯甲醛与丙酮、乙醛与丙酮的反应,3小时后,产物的收率达85%以上,操作十分简便.
Solid base as catalyst in aldol condensation has many advantages comparing with liquid base : Such as (1) the reaction condition was mild; (2) the catalytic activity was high ;(3) final treatment was easy ;(4) the yield was good and the supported reagent could be reused .During experiment , NaOH/Al2O3 as catalyst in the reactions of benzaldenyden and acetone or acetaldehyde and acetone , after 3 hours,the yield was beyond 85%.The operating was very easy.
