Versuchsvorschrift

1.74 g of fumaric acid was dissolved in a mixture solvent having 100 cm3 of methanol and 8 cm3 of formic acid. Then, under stirring at the normal temperature, into the above solution, a further solution in which 3.38 g of formic acid copper was dissolved in 100 cm3 of methanol was dripped. After this solution was left still for one day, the precipitation product was suction-filtered and dried for 120° C./4 hours, whereby 1.23 g of fumaric acid copper was obtained. This substance had the specific surface area of 480 m2 /g.
