Alcoholysis, saponification and the preparation of fatty acid methyl esters
Evidence is offered to support the contention that methanolysis precedes the saponification of esters in methanolic solutions of sodium hydroxide. This results from the hydroxide-alkoxide equilibrium which greatly favors methoxide formation even in the presence of rather considerable amounts of water. Saponification-reesterification methods of methyl ester formation are shown to be actually extensions of methanolysis procedures. A simplified method is proposed for the preparation of fatty acid methyl esters.
