固体超强酸SO2-4/ZrO2催化合成环己酮甘油缩酮
Synthesis of cyclohexanone glycerol ketal catalyzed by solid superacid catalyst SO42-/ZrO2
摘要
Abstract
The solid superacid catalyst SO2-4/ZrO2 is prepared by impregnation and characterized by X-ray diffraction, thermogravimetric analysis and scanning electron microscope. The condensation reaction of cyclohexanone with glycerol catalyzed by SO42 -/ZrO2 is studied. The influence of the cyclohexane dosage, the reaction time, the molar ratio of cyclohexanone to glycerol and the catalyst amount on the cyclohexanone glycerol ketal yield is also investigated. The experimental results show that SO2-4/ZrO2 calcined at 600 ℃ has the highest acidity and good performance in the synthesis of cyclohexanone glycerol ketal. Under the optimum reaction condition of the reaction temperature of 100 ℃, n ( cyclohexanone ): n ( glycerol ) = 1: 2. 5, m (catalyst): m ( glycerol ) = 0. 05, m ( cyclohexanone): m(glycerol) =0. 2, and the reaction time of 2 h, the cyclohexanone glycerol ketal yield is more than 85.0%.关键词
