In this study, the synthesis of bis‐(2‐ethylhexyl) terephthalate, via the transesterification reaction of dimethyl terephthalate (DMT) by 2‐ethylhexanol in the presence of different heterogeneous catalysts, such as Pb(OAc) 2 ·3H 2 O, Cd(OAc) 2 ·2H 2 O, Zn(OAc) 2 ·2H 2 O, Hg(OAc) 2 , Ca(OAc) 2 ·H 2 O, Cu(OAc) 2 ·H 2 O, NaOAc, CaCO 3 , CaO, ZnSO 4 ·7H 2 O, and sulfated zirconia, has been investigated. The reactivity of the catalysts in the reaction progress has been studied and compared. It was found that, hydrated cadmium acetate and sulfated zirconia were reactive catalysts to this reaction. The extent of transesterification of methyl ester groups reached up to 93% and 85.6% using these catalysts, respectively.
