Hydroformylation of higher olefin catalyzed by water-soluble rhodium-phosphine catalyst in ionic liquid

从离子液体/有机两相催化体系、固定化离子液体多相催化体系、离子液体/超临界二氧化碳催化体系等,总结了离子液体在水溶性铑膦络合物催化长链烯烃氢甲酰化反应的应用.与传统溶剂相比,离子液体不仅是传统意义上的反应介质,而且还具有促进反应活性和选择性、简化催化剂与产物的分离等功能.

As novel environmentally friendly solvents and catalysts, ionic liquids have been received increasing recognition and acceptance. They exhibited great potential advantages in the development of novel catalytic technologies of organic synthesis with better yield and selectivity. The applications of ionic liquids in the hydroformylation of higher olefins were summarized, which included ionic liquid-organic biphasic system, supported ionic liquid-phase catalytic system, ionic liquid-scCO2 biphasic system. In the hydroformylation of higher olefins, ionic liquid can not only exert the effects as the traditional reaction medium, but also can achieve the functions such as enhance reaction activity and selectivity, simplify separation of catalyst from product, support and activate catalyst.
