Commercial grade material may be grayish-black powder or lump (the color is due to presence of calcium carbide and other impurities); density 2.29 g/cm3; melts around 1,340°C; sublimes around 1,150 to 1,200°C on rapid heating; reacts with water.
  • Uses Manufacture of calcium cyanide and dicyandiamide; formerly used as a defoliant and herbicide Calcium Cyanamide is used as a fertilizer, herbicide, insecticide, a steel-making additive and an ore processing material. It can also be used to make thiourea, guanidine and ferrocyanides. manufacture of calcium cyanide, melamine, dicyandiamide. Calcium cyanamide has its major use as a fertilizer. However, it has a number of other uses, such as a herbicide and a defoliant for cotton plants. It is finding increasing use as a chemical intermediate. For example, it is being used to produce dicyandiamide, which in turn can be polymerized to form the widely used monomer, melamine. The conversion to calcium cyanide and hence into a variety of other uses is also important commercially.
Technology Process of Cyanamide

There total 101 articles about Cyanamide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
