A process for the preparation of triethylene glycol dicarboxylic acid esters

The invention discloses a preparation method of triethylene glycol dicarboxylate which has a structural formula (I). The method comprises the following step: in the presence of a catalyst containing anhydrous potassium carbonate, triethylene glycol with a structural formula (II) reacts with carboxylate RCOOR1 and R'COOR1 to generate products containing triethylene glycol dicarboxylate with the structural formula (I) and corresponding alcohol HOR1, wherein R and R' are the same or different and are respectively and separately selected from one of linear C2-C17 alkyl groups and branched C3-C17 alkyl groups and C4-C8 naphthenic groups; and R1 is one selected from C1-C5 alkyl groups. The method provided by the invention is beneficial to environmental protection and has advantages of high product yield and good purity.
