Zinc cyanide Wikipedia

Zn(CN)2 is fairly easy to make by combining aqueous solutions of cyanide and zinc ions, for example via the double replacement reaction between KCN and ZnSO4: ZnSO4 + 2 KCN → Zn(CN)2 + K2SO4For commercial applications, some effort is made to avoid halide impurities by using acetate salts of zinc: Zn(CH3COO)2 + HCN → Zn(CN)2 + 2 CH3COOH
