摘要
铑/膦催化剂的分离循环是影响高碳烯烃氢甲酰化工艺经济性的关键因素。均相体系中,由于高碳醛沸点高,传统热分离易引起催化剂不可逆失活。若采用液/液两相体系,高碳烯烃传质受限使反应效率显著降低。因此,催化剂的分离循环成为工业化的瓶颈。梳理了高碳烯烃氢甲酰化工业应用现状,重点综述了近年来铑/膦催化剂在均相和液/液两相体系中分离循环的研究进展以及新型反应工艺在氢甲酰化反应中的应用,为推进铑/膦催化剂在高碳烯烃氢甲酰化中的工业应用提供指导。
The separation and recycling of rhodium/phosphine catalysts are a key factor influencing the economy of higher olefin hydroformylation processes.In homogeneous systems,the high boiling point of high-carbon aldehydes tends to induce irreversible deactivation of the catalysts during conventional thermal separation.If the liquid/liquid biphasic systems are adopted,the mass transfer limitations of higher olefins significantly reduce reaction efficiency.Therefore,the catalyst separation and recycling technology has become the bottleneck for industrial popularization.This paper summarized the current industrial application status of higher olefin hydroformylation,with the focus on reviewing the research progress in the separation and recycling for rhodium/phosphine catalysts in both homogeneous and liquid/liquid biphasic systems in recent years,as well as the application of new reaction processes in hydroformylation reactions.Finally,theoretical guidance is provided for advancing industrial applications of these catalysts in higher olefin hydroformylation.
