2.58 g of 1,4-trans-cyclohexane dicarboxylic acid was dissolved under heating in a mixture solvent of 100 cm3 of methanol and 20 cm3 of formic acid. After this solution was cooled to the normal temperature, into this solution under stirring, a further solution in which 3.38 g of formic acid copper was dissolved in 100 cm3 of methanol was dripped and then this was kept still for a few days. Thereafter, the precipitation product was suction-filtered and dried for 110° C./4 hours, whereby 1.43 g of 1,4-trans-cyclohexane dicarboxylic acid copper was obtained.
