Reaction Steps

A mixture of 1,2-cyclohexanedicarboxylic anhydride (60 g), hexanol (85 g), and p-toluenesulfonic acid (100 mg) in toluene (500 mL) was refluxed for 3 days and water removed from the reaction mixture. After reaction was complete, solvent was removed in vacuo to yield a viscous oil. The crude material was redissolved in heptane and passed through a pad of silica gel to obtain cyclohexane-1,2-dicarboxylic acid dihexyl ester (80 g) as a pale yellow oil.
