How is Cyanamide, cyano-, zinc salt (CAS: 18622-28-1) typically synthesized?

Cyanamide, cyano-, zinc salt is typically synthesized by reacting zinc nitrate with sodium cyanamide in aqueous solution. The process involves the formation of zinc cyanamide, which is then precipitated and treated with a zinc salt to form the desired zinc salt. The reaction is exothermic and requires appropriate temperature and pH control to achieve high yields and selectivity. Commonly used catalysts include sodium hydroxide or other bases to ensure the reaction proceeds efficiently.
