Zusammenfassung:	Process for improving the color and the stability of the color of carboxylic acid (advantageously fatty acids and resin acids) or a mixture of the same by treating the carboxylic acid or its mixture with a hydride - yielding substance (e.g. sodium borohydride and lithium aluminium hydride) at an elevated temperature and by distilling the mixture thus obtained.
