摘要
采用红外光谱分析法,详细研究了温度、催化剂等条件对环己酮与过氧化氢反应生成三聚环己酮过氧化物的影响。在10～35℃范围内,随着反应温度的增高,杂质(二聚环己酮过氧化物)的相对含量呈反S型曲线增加,产率在20℃左右呈现极大值,达89％。用化学分析法研究反应动力学,表明其为二级反应,反应活化能为5.78×10~4焦耳/摩尔。三聚环己酮过氧化物在国产高沸点溶剂中进行热分解,于175±5℃,反应1小时达平衡,环十六内酯产率达25％。
The effects of temperature and catalyst on reaction of synthesis of cyclic triperoxide of cyclohexanone from cyclohexanone and hydroperoxide have been investigated by using IR. It has been found that when the temperature is raised in 10-35℃, relative content of the byproduct (cyclic diperoxide of cyclohexanone) is increased as opposite-S-type curve; that the yield appears maximum at around 20℃, it reaches 89%. The reaction kinetics also has been investigated by chemical analysis. It was proved that the reaction is a second order one and apparent activation energy is 57.8kJ/mol.Thermolysis of triperoxide was carried out in native petroleum solvent. It reaches equilibrium at 175±5℃ in 1 hour. The yield of hexadecanolide is 25%.
