Procedure

0.41 g of terephthalic acid was dissolved under heating in a mixture solvent of 250 cm3 of methanol and 15 cm3 of formic acid. After this solution was cooled to the normal temperature, into this solution, a further solution in which 0.50 g of copper acetate was dissolved in 40 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 0.38 g of terephthalic acid copper was obtained.
