以水溶性离子液体[Bmim]BF4和水作为混合溶剂、RhCl3/TPPTS为催化剂进行1-丁烯氢甲酰化反应.产物可方便地通过重力沉降分离,戊醛的正-异比达9.1∶1 (V∶V)催化体系经5次循环,催化活性未见明显降低.

关键词: 氢甲酰化, 离子液体, 1-戊醛, 1-丁烯

Hydroformylation of 1-butene was carried out in [Bmim]BF4/H2O using RhCl3/TPPTS as catalyst. The high selectivity for the n-product was obtained (n/iso ratio up to 9.1). The catalyst/solvent system could be reused, and THE catalytic activity was not decreased obviously after 5 times recycle.

Key words: hydroformylation, ionic liquid, 1-pentanal, 1-butene
