PROCESS FOR THE PURIFICATION OF CARBOXYLIC ACIDS

摘要

A process for the purification of carboxylic acid having a chain length from one to five carbon atoms is disclosed herein. The process includes transforming the carboxylic acid to its monoester and/or its diester, and processing the mono- and/or the diester of the carboxylic acid by subcritical or supercritical fluid chromatography using a subcritical or supercritical mobile phase.
