Abstract
A process for separating a first component of a composition from a second component of a composition. The process involves contacting the composition with a supercritical fluid comprising 1,1,1,2-tetrafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane, or a mixture thereof, in the supercritical state under conditions and for a time sufficient to remove the first component from the composition.
