【摘要】 综述了近年来环己酮氧化制备ε-己内酯的工艺研究进展并评述了各工艺的优缺点。以环己酮为原料氧化制备ε-己内酯的工艺主要有过氧酸氧化、双氧水氧化、氧气/醛类共氧化和生物氧化等4种氧化工艺,其中过氧酸、双氧水为氧源氧化环己酮制备ε-己内酯的技术已被人们成功掌握。过氧酸氧化法是目前工业大规模生产ε-己内酯的主流。但是,基于当今绿色化学的要求和发展现状,双氧水氧化工艺是最经济和具有发展前景的制备ε-己内酯的工艺,需研发高效稳定的催化剂及其工艺中的除水技术。更多还原

【Abstract】 The research progress in the preparation of ε-caprolactone by cyclohexanone oxidation were reviewed in recent years, as were the advantages and disadvantages of the production processes. The preparation of ε-caprolactone by cyclohexanone oxidation includes four types of oxidation processes: peroxy acid oxidation, hydrogen peroxide oxidation, oxygen/aldehyde co-oxidation and biological oxidation. Among them, the technology of preparing ε-caprolactone by oxidizing cyclohexanone with peroxy acid and hydrogen peroxide has been successfully mastered. Peroxy acid oxidation is the mainstream of large-scale industrial production of ε-caprolactone. However, based on the requirements and development status of green chemistry, the oxidation process of hydrogen peroxide is the most economical and promising process for the preparation of ε-caprolactone. It is necessary to develop efficient and stable catalysts and water removal technology in the process.更多还原
