Abstract

A process for separating a multi-component mixture containing solid or liquid organic components by treating the mixture with a gaseous entraining agent comprising a superheated carrier fluid containing a lower monohydric alcohol or a lower monohydric alcohol and water to cause constituents of the multi-component mixture to become entrained in the gaseous entraining agent, and separating the gaseous entraining agent containing constituents of the multi-component mixture from the multi-component mixture.
