ABSTRACT:
A process is disclosed for converting lower alkyl esters of fatty acids to the corresponding fatty acids by the steps of sequentially dissolving the esters in a solvent, saponifying the solution, acidifying the solution to a pH of between about 5 and about 8, distilling to remove solvents, and again acdifying the solution to a pH of between about 1 and about 4. The acids may then be removed by washing.
