VERFAHREN ZUR HERSTELLUNG VON FETTSAUREN, AUSGEHEND VON SEIFEN

摘要

Fatty acids are made from corresponding carboxylate soaps by a method which comprises dissolving the soaps in at least one fatty acid in a melted state in the absence of oxygen, contacting the liquid solution of soap in fatty acid with an aqueous solution containing an amount of strong mineral acid at least stoichiometrically equivalent to the soap and allowing the cations of soap and strong acid to exchange phases, the amount of water being just sufficient to dissolve substantially all of the mineral salt thus formed.
