摘要:

综合介绍了多种烯烃水合反应的机理、生产工艺及催化剂的研究成果。分类详细归纳了环己烯、丙烯、高碳烯烃等通过水合反应生产相应产物醇的生产工艺和催化剂的最新研究进展,并分析了烯烃水合技术的未来发展趋势。分析发现:烯烃水合反应的路径主要分为直接路径和间接路径;其反应机理主要有马氏规则的亲电加成机理、反马氏规则的亲电加成机理、自由基反应机理等;烯烃水合反应用催化剂从液体酸、碱,过渡金属盐或氧盐,不断向分子筛、固体酸、合成树脂、光催化剂、酶催化剂方向发展。未来,光催化和生物酶催化是烯烃水合科技研究的重点方向;而反应设备参数优化、提升催化剂性能、强化物料混合效果、改善传质过程等,则是烯烃水合生产工艺优化的发展趋势。

Abstract:

Researches of the mechanism, process and catalysts for various olefin hydration reactions were reviewed. The latest progress in the processes and catalysts of cyclohexene hydration to produce cyclohexanol, propylene hydration to produce isopropanol, and high-carbon olefin hydration to produce high-carbon alcohol were summarized in detail, together with the development trend of olefin hydration reaction in the future. The reaction pathways of olefin hydration could be mainly divided into direct and indirect ones, and the reaction mechanisms were mainly the electrophilic addition mechanism of martensitic rule, the electrophilic addition mechanism of anti-martensitic rule and the radical mechanism. The olefin hydration catalysts are changing from liquid acid, alkali, transition metal salt or oxygen salt, to molecular sieve, solid acid, synthetic resin, photocatalyst and enzyme catalyst. In the future, photocatalysis and enzyme catalysis will be the key research directions of olefin hydration technology, and the optimization of reaction equipment parameters, the enhancement of catalyst performance, and the improvement of material mixing and mass transfer are the development trends of olefin hydration process optimization.

Key words: olefin, hydration, alcohol, molecular sieve, catalyst, selectivity
