主　　题：PEG1000 CO2 n-Butanol Phase behavior Separation 

摘      要：The phase behavior of supercritical (SC) CO2 + PEG 1000 (PEG with average molecular weight of 1000 g/mol) + n-butanol system was studied. It was demonstrated that SC CO2 could induce phase separation of PEG 1000 + n-butanol system under suitable conditions. This hints that SC CO2 has potential applications in the separation of mixtures of PEG + organic compound.
