Procedure

To a reaction flask was charged 19.93 g (0.120 mole) of phthalic acid, 100 g of ethanol and 0.50 g of tetraethylammonium chloride hydrate. Copper foil was used as the anode and a graphite rod as the cathode. After passing 9,964 coulombs of electricity, 3.0 g (0.047 mole) of copper was consumed. The solvent was stripped off at reduced pressure to give a blue solid of copper phthalate containing 25.25% copper.
