A new process for the production of linear monocarboxylic acid esters with 6 to 26 carbon atoms, by reaction of vegetable oils or animal oils that may or may not be neutral, with monoalcohols of 1 to 18 carbon atoms, uses a catalyst that is selected from among:n the combinations of zinc oxides and titanium oxides; the combinations of zinc oxide, titanium oxide and alumina; the combinations of bismuth and titanium oxides; and the combinations of bismuth oxide, titanium oxide and alumina. nn The process makes it possible to produce directly, in one or more stages, an ester that can be used as a fuel and a pure glycerin. |
