Zusammenfassung:1. A process for the preparation of a wax ester, made from an optionally partially-hydrolyzed hard paraffin oxidate of synthetic origin on the one hand and a monohydric or polyhydric alcohol on the other hand, in the melt under mild conditions with substantial to complete esterification of the oxidate, characterised in that the reaction is carried out at 140 to 220 degrees C in the presence of 0.01 to 3.0% by weight of zinc compound, relative to the amount of hard paraffin oxidate employed, with addition of half to twice the stoichiometric amount of alcohol relative to the acid number and removal of the water of reaction as steam, at least 70% of the wax acid, determined by the acid number, being esterified and the acid number of the wax ester formed simultaneously being reduced to below 10 mg of KOH/g.
