PROCESS FOR THE PURIFICATION OF CARBOXYLIC ACIDS BY SUBCRITICAL OR SUPERCRITICAL FLUID CHROMATOGRAPHY.

摘要

Process for the purification of carboxylic acid having a chain length from one to five carbon atoms comprising the steps of transforming the carbocylic 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.
