Abstract
The present invention relates to an improved process for preparing fatty acids from alkyl, preferably methyl esters via acid hydrolysis by using ratios of water/ester/acid catalyst to form single phase reaction mixtures wherein the initial stoichiometric ratio of water to ester is at least about 1:1. These ratios are represented by the ternary phase diagram of FIG. 1 for a preferred C.sub.6 -C.sub.14 alkylbenzene sulfonic acid catalyst having mid-point attachment of the alkyl chain to the benzene ring.
