摘要：对在氢氧化钠水溶液催化作用下的丙酮与柠檬醛缩合生成假性紫罗兰酮这个反应体系,研究了均相与液液非均相状态下的动力学特性,得到了反应动力学的总关联式(?)并获得了均相与非均相反应的活化能,分别为106、48和37.24kJ/mol,同时讨论了均相与非均相体系对反应结果的影响。
The condensation reaction of citral with acetone catalyzed by aqueous sodium hydroxide solution to give pseudoionone was studied in detail.The kinetics of homogeneous and heterogeneous reactions were studied and a rate equation derived from Hougen-Watson method is as follows: d[P_p]/dt={k_1βk_3β[A][OH^-][C]/(k_2β[H_2O])}{(R_v+1)(R_vξ_4+1) /[(R_vξ_1+1)(R_v·ξ_2+1)]} The activation energy of this aldol condensation reaction is 106.48 kJ/mol for homogeneous system and 37.24 kJ/mol for liquid-liquid two phase heterogeneous system.
