Claims (6)
1. A process for the separation of fatty acids which process comprises mixing the fatty acids with an organic solvent for the fatty acids and cooling the mixture by direct expansion at atmospheric pressure of a liquefied refrigerating agent, which refrigerating agent is gaseous at atmospheric I3 . il.i97¾ pressure to cause the acid of higher freezing point to crystallise while the other acid or acids remain in solution*
2. A process according to claim 1 wherein the organic solvent is methanol.
3. A process according to claim 1 or 2 wherein the refrigerating agent is a halogenated hydrocarbon,
4. A process according to claim 5 wherein the refrigerating agent is methyl chloride, dichlorofluoromethane* dichlorodi- fluoromethane or Chloretrlfluoromethane.
5. · A process according to any one of the preceding claims wherein the fatty acids to be separated are stearic and oleic acids ·
6. A process according to any one of the preceding claims 13 11 197¾ wherein the mixture of fatty acids and organic solvent JUBBC I admitted t a column at or adjacent to the top of the column ( and the low boiling refrigerating agent is admitted to the ( column adjacent to the bottom of the column. ( 7· A process according to any one of the preceding claims rein the organic solvent and the low boiling refrigerating nt are recovered and used in a subsequent separation process* 8· A process for separating fatty acids substantially as described with reference to the accompanying drawing, 9* A fatty acid separated from a mixture of fatty acids by a process as elaimed in any one of the preceding claims.
