概要
- 論文の詳細を見る
In manufacturing dicyandiamide directly from crude calcium cyanamide, free cyanamide is first produced by the reaction between gaseous anhydride of a week acid, such as carbon dioxide, and crude calcium cyanamide in the presence of a very small amount of water, which is then changed into dicyandiamide by heating and then extracted with liquid ammonia. The method is simple and gives the product of high purity with high yield.
