The present invention relates to a process for the production of alkyl esters of carboxylic acids for use as biodiesel starting from the reaction of transesterification of triglycerides originating from oils and fats of vegetable or animal origin, which can be used individually or in mixtures with one another in any proportions, employing heterogeneous catalysis by means of protonated lamellar titanate catalysts in nanostructured form, and said forms can comprise, among other forms, nanotubes, nanofibres or nanosheets. La présente invention a pour objet un procédé de production d'esters alkyliques d'acides carboxyliques pour une utilisation comme biodiesel. Ce procédé commence par la réaction de transestérification de triglycérides provenant d'huiles ou de graisses d'origine végétable ou animale, qui peuvent être utilisés seuls ou en mélanges de proportion quelconque, par catalyse hétérogène au moyen de catalyseurs de titanate lamellaire protoné sous forme nanostructurée, ladite forme peut comprendre, entre autres, des nanotubes, des nanofibres ou des nanofeuilles.
