摘　　要：使用超音速气流对羟基苯甲醛和对氨基苯甲酸在反应器中摩擦活化,再通过撞击固定靶产生迅速的能量交换而发生化学反应,成功实现了超音速气流低热固相反应制备Schiff碱。讨论了循环次数以及反应压力对产物产率的影响,实验结果表明在反应压力0.2 MPa下,原料只需反应6min即可完全转化,相比于其他方法反应时间大为缩短。Using supersonic speed airflow to activate p-hydroxybenzaldehyde and p-aminobenzoic acid in reaction zone, and make the reagents impact on a certain fixed target to react by the exchange of rapid energy through impacting is applied to preparation of Schiff base. The influence of the reaction number and reaction pressure on the yields of product is further studied. The results show that the yield can achieve 100% within 6min amd under reaction pressure of 0.2 MPa. Compared with other methods, the solid-state reaction under supersonic speed airflow and low-heating can greatly reduce the reaction time.
