70 ml of diethylene glycol was added to 8 g of anhydrous copper acetate (manufactured by Wako Pure Chemical Industries, Ltd.). Thereto was added 2.6 ml of 64 wt % hydrazine hydrate at room temperature of 25° C. while stirring so as to give a molar ratio of hydrazine and copper acetate of 1.2, thereby to carry out the reaction. As a result, the resulting precipitate was not cuprous oxide, but copper.
