Abstract
A method of preparing a composition of alcohol esters of linear monocarboxylic acids with 6 to 26 carbon atoms from a vegetable or animal oil, neutral or acid, virgin or recycled, with monoalcohols having 1 to 18 carbon atoms, in the presence of a catalyst of nitrogen-containing metallophosphate type.
