Product details

Monocyanamide can be prepared by using lime nitrogen (CaCN2) as raw material and interacting with sulfuric acid. Put water in the reaction kettle, cool with ice brine, add lime nitrogen, keep the temperature between 0 ～ 15 ℃, add 5% sulfuric acid solution dropwise, adjust pH = 6, keep for 20min, filter, wash with water, then return to the reaction kettle Then, add lime nitrogen and repeat the above operation twice, and the obtained filtrate is concentrated by a film to maintain a certain temperature. After concentration, the content reaches 50% to 55% to obtain a 50% cyanamide solution. Reaction equation:CaCN2 +H20 + H2S04 NH2 CN + CaS04

It can also be prepared by reacting calcium cyanamide with carbon dioxide and water,

CaCN2 +H20 + C02 —+ H2 NCN + CaC03
