A novel thermoregulated phosphine ligand used for the Rh-catalyzed hydroformylation of mixed C11-12 olefins in aqueous/organic biphasic system
摘要:
A novel thermoregulated phosphine ligand Ph2P(CH2CH2O)nCH3 (n=22) was synthesized and used for the Rh-catalyzed hydroformylation of mixed C11-12olefins in aqueous/organic biphasie system. Under the optimized conditions, pressure=5 Mpa (H2:CO=1:1), phosphine/Rh=13 (molar ratio), reaction time=6 h and temperature=130℃, the conversion of C11-12 olefins and the yield of aldehyde are 99% and 94%, respectively. The catalyst retained in aqueous phase can be easily separated from the product-containing organic phase by simple phase separation and the catalytic activity remains almost constant after four consecutive cycles.
