The C₁-C₁₈ alkyl oleates were prepared in n-hexane by esterification of oleic acid with either the primary and secondary C₁-C₆ alcohols or the primary fatty C₈-C₁₈ alcohols. The esterification was acid-catalyzed in the presence of p-toluene sulfonic acid (p-TSA) in a pseudo-homogeneous phase, or in the presence of the sulfonic macroporous resin (K2411) in the heterogeneous phase. The purified alkyl oleates were characterized by ¹³C-NMR. The oleic acid/alkyl oleate mixtures were analyzed by high-performance liquid chromatography (HPLC).
