Calcium cyanamide - Wikipedia

The process was particularly challenging due to the equipment requirements required by the high temperatures during the initial igniter step. This process requires meticulous temperature control since the melting point of calcium cyanamide is only about 120°C lower than the boiling point of sodium chloride. In 1901, Ferdinand Eduard Polzeniusz patented a process that converts calcium carbide ...

CALCIUM CYANAMIDE HAZARD SUMMARY - New Jersey

Calcium Cyanamide is a colorless to gray crystalline (sand-like) material or a powder. It is used to make Calcium Cyanide and Dicyandiamide, and to desulfurize steel. REASON FOR CITATION * Calcium Cyanamide is on the Hazardous Substance List because it is regulated by OSHA and is cited by ACGIH, DOT, NIOSH, DEP and EPA. * This chemical is on the Special Health Hazard Substance List because

Frank–Caro process - Wikipedia

The Frank–Caro process, also called cyanamide process, is the nitrogen fixation reaction of calcium carbide with nitrogen gas in a reactor vessel at about 1,000°C. The reaction is exothermic and self-sustaining once the reaction temperature is reached. Originally the reaction took place in large steel cylinders with an electrical resistance element providing initial heat to start the reaction.

Calcium Cyanamide - an overview ScienceDirect Topics

Calcium acetylide is used in the manufacture of calcium cyanamide, CaCN 2, by the reaction of CaC 2 with N 2 at high temperature. (11.46) CaC 2 + N 2 → 1000 ∘ C CaCN 2 + C As in the case of the Haber process for the synthesis of ammonia, this reaction represents a way of converting elemental nitrogen into a compound (nitrogen fixation).

Cyanamide 99% Hydrogen cyanamide Sigma-Aldrich

Cyanamide in aqueous solution or in the form of its calcium salt is used as a fertilizer in agriculture. It is a potent inhibitor of liver aldehyde dehydrogenases in vivo. Application Cyanamide was used as nitrogen source in thermal transformation of metal oxide nanoparticles into nanocrystalline metal nitrides.

Calcium carbide - Wikipedia

Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.Its main use industrially is in the production of acetylene and calcium cyanamide.. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide ...

How to Make Cyanide - Mineral Processing Metallurgy

Calcium cyanamide is also formed in the electric resistance furnace by passing nitrogen over a mixture of lime and charcoal: CaO + 2C + N2 = CaCN2 + CO. By heating the product at a high temperature with a further quantity of carbon, with the addition of salt-to prevent frothing and facilitate the reaction, the cyanamide is converted into cyanide as follows: CaCN2 + C = Ca(CN)2. The crude ...
