磺化聚苯硫醚—铑配合物催化的氢甲酰化

Research on the Sulfonated Polyphenylene Sulfide Rhodium Complexes Catalyzed Hydroformylation Reaction

光电子能谱对水溶性碘化聚苯硫醚—铑配合物催化剂的测定结果表明,其中铑的价态为Rh^1,以链节/金属摩尔比为5的该配合物为催化剂,在互不相溶的水/有机溶剂二相介质中对十一烯酸甲酯的氯甲酰化反应进行了初步研究,考察了不同的温度、压力、pH值等反应条件对氢甲酰化反应的影响,在P_(H3)为1～3MPa内,随着氢分压的增大,产物的转化率和正异构比都随之增加,水相最佳反应pH值为8。

The water-soluble sulfonated polyphenylene sulfide rhodium complexes were vued as catalysts in hydroformylation of methyl w-undecylenoate in liq. -Liq. two immiscible phases system. The effects of different condition were examined on the hydroformylation reaction.
