実験手順

1.2 g of fumaric acid was dissolved under heating in a mixture solvent of 100 cm3 of methanol and 12 cm3 of formic acid. After this solution was cooled to the normal temperature, into this solution, 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 one day. Thereafter, the precipitation product was suction-filtered and dried for 120° C./4 hours, whereby 1.37 g of fumaric acid copper was obtained.
