The present invention refers to a process of transesterification of mono-, di and triglycerides present in vegetable oils and animal fats, which are transesterified with alcohols of 1 to 3 carbon atoms making use of basic solid heterogeneous catalyzers, being the products of the reaction used as fuel or additive for fuel, as solvents, as intermediaries of tensoactives or as detergents . L'invention concerne un procédé de transestérification de mono-, di et triglycérides présents dans des huiles végétales et des graisses animales, lesquels sont transestérifiés au moyen d'alcool constitués de 1 à 3 atomes de carbones au moyen de catalyseurs hétérogènes solides de base, ceux-ci étant les produits de la réaction utilisée comme combustible ou additif de combustible, comme solvants, comme intermédiaires de tensioactifs ou comme détergeants.
