METHOD FOR PREPARING ALCOHOL ESTERS FROM TRIGLYCERIDES AND ALCOHOLS USING A HETEROGENEOUS CATALYST CONTAINING A MESOSTRUCTURED ZINC SILICIC SOLID

摘要

The invention relates to a catalytic method for preparing a composition of alcohol esters of linear monocarboxylic acids having 6 to 26 carbon atoms, from a vegetable or animal oil that is neutral or acidic, virgin or recycled, with monoalcohols having 1 to 18 carbon atoms, in the presence of a catalyst containing a mesostructured zinc silicic solid, which can be used in a pure form or in the presence of binders such as, but not exclusively, alumina, silica or clays.
