摘要：对丙酮(A)和柠檬醛(C)在NaOH水溶液(W,NaOH)的催化作用下,生成假性紫罗兰酮(P)反应进行了液液相平衡研究。测定了A-C-W扣A-P-W体系的相图,並用改进渐近滴定法直接测得了A-C-W(NaoH)的溶解度曲线。在三元相图研究的基础上对该体系的反应过程进行了分析。
The phase equilibrium of aldol condensation reaction between citral and acetone catalyzed by aqueous sodium hydroxide solution was studied. Some phase diagrams of acetone-citral-water system snd acetone-pseudoinone-water system were presented, while the solubility curves of acetone-citral-water containing a few percent of sodiun hydroxide were measured by an improved gradual titration method. According to the results obtained, the mechanism of this aldol condensation reaction was analysed.
