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.
