Procedure

1.74 g of fumaric acid and 40 cm3 of acetate were dissolved under heating in 100 cm3 of methanol, and into this solution, 100 cm3 of methanol solution containing 2.98 g of copper acetate dissolved therein was dripped. After this solution was left still for two days at the room temperature, the precipitation product was suction-filtered and dried for 110° C./3 hours, whereby 1.37 g of fumaric acid copper was obtained. In this case too, the obtained substance had a large specific surface area and exhibited adsorption capacity for methane.
