The invention relates to a process for the preparation of benzoic acid esters with a high selectivity, a high yield of the desired product, and a reduction in the duration of the esterification process, said process consisting in esterification of the acid benzoic acid with monohydric alcohols having a carbon number of 6 to 12, or polyhydric alcohols having a number of carbon atoms of 2 to 10, in the presence of a metal-containing catalyst in an aromatic solvent medium with a gradual increase of the process temperature to 180-200 ° C, then to 200-220 ° C, then 240-250 ° C. |
