Procedure

2-Propylheptyl alcohol (8.1 mol), dimethylcyclohexane-1,4-dicarboxylate (DMCD, cis 1.7%, trans 98.3%, Eastman, 3.0 mol) and tetraisopropyl titanate catalyst (0.85 g) were added to a 2.5 L reactor equipped with a stirrer and two condensers and heated to 185° C. Di(2-propylheptyl)cyclohexane-1,4-dicarboxylate (cis 3%, trans 97%) was obtained with a purity of 99.8% in the same manner as in Example 1.
