The phase behavior of supercritical (SC) CO₂+PEG1000 (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.
