Useful:

• Chemical Classes: Nitrogen Compounds -> Nitriles
• Canonical SMILES: C(#N)C#N
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system. This may result in respiratory failure and collapse. Exposure far above the OEL could cause death.
• Uses: Cyanogen has limited applications, the most important of which are in organic synthesis. Also, it is used in welding metals; as a fumigant; and in some rocket propellants. Cyanogen is used as a fumigant, as a fuel gas for welding and cutting metals, as a propellant, and in organic synthesis. It occurs in blast-furnace gases. It is also known to occur at varying concentrations in cassava flour consumed in northern Mozambique. Organic synthesis; fuel gas for welding and cutting heat-resistant metals; rocket and missile propellant; fumigant

Technology Process of Cyanogen

There total 314 articles about Cyanogen 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:

Reference yield: 75.0%

silver(I) cyanide (506-64-9) → ethanedinitrile (460-19-5,25215-76-3)

Guidance literature:

In neat (no solvent); at 350 ℃;

DOI:10.1016/S0022-2860(97)00093-8

Reference yield: 38.0%

potassium cyanide → ethanedinitrile (460-19-5,25215-76-3)

Guidance literature:

With copper(II) sulfate; In water; byproducts: CuCN, K2SO4; An aq. soln. of KCN is dropped onto solid CuSO4*5H2O in a dry N2 atmosphere.; The gaseous products are passed through an ice/NaCl-cooled trap, through a tube filled with CaCl2 and finally condensed in a trap held at -80°C. The crude product is passed through a tube with solid NaOH to eliminate HCN.;
