Preparation of zinc cyanide

100 grams of sodium cyanide are dissolved in 125 ml of water and 150 g of anhydrous zinc chloride in the minimum volume of 50% ethyl alcohol. It is important to ensure an excess of zinc chloride over sodium cyanide in order to prevent the formation of the precipitation of zinc cyanide as a sticky mass. The sodium cyanide solution is added rapidly, with agitation, to the zinc chloride solution. The precipitated zinc cyanide is filtered off under suction, drained well, washed with ethyl alcohol and then with ether. The obtained zinc cyanide is dried in a desiccator or in an air at 50° C, and preserved in a tightly stoppered bottle. The yield of zinc cyanide is almost quantitative with a purity of 95-98%.
