摘要： In order to produce a composition of esters of linear monocarboxylic acids containing 6 to 26 carbon atoms and glycerine simultaneously with high degrees of purity, the following is carried out:a step a) in which a plant or animal oil, which may or may not be acidic, is reacted with an excess of at least one aliphatic mono-alcohol containing 1 to 4 carbon atoms in the presence of a heterogeneous catalyst, eliminating the excess mono-alcohol and separating out glycerine, this step producing a crude ester containing residual mono-glycerides;a step b) in which the crude ester obtained undergoes transesterification or esterification of the residual mono-glycerides to di- and tri-glycerides, in the presence of a heterogeneous catalyst; anda step c) in which the ester composition is evaporated under reduced pressure, recycling the evaporation residue to the starting oil of step a). The ester compositions obtained, which are of high purity, are of particular use as gas oil substitutes.
