Abstract

The esterification of homologous series of fatty acids, aliphatic and aromatic di- and polycarboxylic acids, with aliphatic alcohols in the presence of water and a mineral acid as catalyst, is described. The efficiency of derivatization as well as the detector responses, referred to the organic carbon content of the derivatized products, obtained with two alcohols are compared to each other to establish the optimum conditions for various series of acids. The molar ratios of water/alcohol which yielded quantitative esterifications are given, as is the maximum water content of the esterifying mixture permitted in order for esterification to proceed to completion. The optimum conditions for a reasonable ester yield in the presence of anhydrous sodium sulphate are also presented.
