摘要: 将具有“高温混溶、室温分相”功能的离子液体[CH3(OCH2CH2)16N+Et3][CH3SO3] (ILPEG750)与甲苯-正庚烷组成的两相体系用于纳米 Rh 催化的烯烃氢甲酰化反应中, 在优化的反应条件下, 1-辛烯转化率和醛收率分别为 99% 和 91%. 催化剂经简单分相即可与产物分离, 且可连续使用 8 次, 其活性基本保持不变.

Abstract: Rh nanoparticles were investigated as a catalyst for hydroformylation of olefins in thermoregulated ionic liquid/organic biphasic systems composed of an ionic liquid, namely [CH3(OCH2CH2)16N+Et3][CH3SO3] (ILPEG750), and an organic solvent. This enables not only a homogeneous reaction but also easy biphasic separation. Under the optimized reaction conditions, the conversion of 1-octene and yield of aldehyde were 99% and 91%, respectively. The catalyst was easily separated from the product by phase separation and used eight times without evident loss of activity.
