Fischer esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. WebEsterification can increase the volatility of fatty acids, reduce dimerization in the vapor phase, and reduce adhesion. Esterification improves the peak configuration, the separation, and sample detectability. The methyl, ethyl, propyl, iso -propyl, n -butyl, and iso -butyl esters of fatty acids are recommended.
