Water → Cupric acetate

Participants

Reaction Conditions

Reaction Steps

40 ml of purified water and 30 ml of ethanol were added to 8 g of anhydrous copper acetate (manufactured by Wako Pure Chemical Industries, Ltd.). Thereto was added 2.4 ml of 64 wt % hydrazine hydrate while stirring at room temperature of 25° C. so as to give a molar ratio of hydrazine to copper acetate of 1.1, thereby carrying out the reaction to obtain a precipitate of cuprous oxide. The average primary particle diameter and the average secondary particle diameter were 10 nm and 190 μm, respectively. The average secondary particle diameter in the colloidal dispersion, obtained in the same manner as in Example 1, was 40 nm.
