A novel phosphate ligand used for the Rh-catalyzed hydroformylation of cyclohexene in a thermoregulated PEG biphase system
摘要:
A novel phosphate ligand, tri-(methoxyl polyethylene glycol)-phosphate (TMPGPA), has been synthesized and used in the Rhcatalyzed hydroformylation of cyclohexene in a thermoregulated PEG biphase system. Under the optimized conditions, pressure=5 Mpa (H2:CO=1:1), P/Rh=10 (molar ratio), reaction time=4 h and temperature=120℃, the conversion of cyclohexene and the yield of aldehyde are 99%. The catalyst retained in PEG phase can be easily separated from the organic phase containing product by simple phase separation and reused ten times without obvious loss in activity.
