METHOD FOR PRODUCING ALCOHOL ESTERS FROM TRIGLYCERIDES AND ALCOHOLS USING HETEROGENEOUS CATALYSTS CONTAINING A HYBRID SOLID WITH AN ORGANIC-INORGANIC MIXED MATRIX

摘要

The invention relates to a method for making a composition of alcohol esters of linear monocarboxylic acids having 6 to 26 carbon atoms, from oil of a vegetable or animal, neutral or acidic, virgin or recycled type, with monoalcohols having 1 to 18 carbon atoms, in the presence of a heterogeneous catalyst containing a hybrid solid with an organic-inorganic mixed matrix, wherein said method can be used for producing directly, in one or more steps, an ester that can be used as a fuel as well as pure glycerine.
