Synthese
Cupric oxide is heated with 8% acetic acid, As2O3 is added, and the mixture is refluxed for two hours. The product is allowed to cool for half an hour, filtered, washed and dried.Alternate method: Dilute acetic acid is allowed to react with an excess of freshly precipitated Cu(OH)2 and the product is separated by filtration. Dilute acetic acid is added to a solution of As2O3 in boiling NaOH until the color of phenolphthalein disappears. The hot solutions are mixed (mole ratio of CuO:As2O3 = 4:3) and allowed to stand for several days [S. Avery, J. Amer. Chem. Soc. 28, 1159 (1906)].
