Nitrogen Fixation - University of Delhi
“Nitrogen Fixation”is the process that converts the atmospheric nitrogen to useful/simpler compounds of nitrogen. Nitrogen gets “fixed” when it is combined with oxygen or hydrogen. The conversion of N 2to reactive forms of N is nitrogen fixation

Impact of Human Activities on the Nitrogen Cycle
In the second process (known as the cyanamide process), nitrogen is reacted with calcium carbide at high temperatures. The product of this reaction is calcium cyanamide, however, this product is further hydrolyzed to form ammonia and urea. The cyanamide process was widely used by several countries both before and after World War I.
The Ammonia Oxidation Process for Nitric Acid Manufacture
It is little more than fifty years since the first manufacture of nitric acid by the oxidation of ammonia over a platinum catalyst. Ostwald's original industrial plant had an output of some 100 tons of acid a year; today the world capacity for nitric acid manufacture by this process is about ten million tons a year. This article traces the beginnings and early developments of the process ...

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.
Hydrogen cyanide – HCN – Manufacturing process for Hydrogen
Hydrogen cyanide (HCN) is an important chemical with over a million tons produced globally each year. The watery liquid or gas is used in a variety of syntheses including the production of adiponitrile (for nylon), methyl methacrylate, sodium cyanide and chelating agents.

Haber process - Wikipedia
The Haber process, also called the Haber-Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.The process converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction ...
Calcium cyanamide - Wikipedia
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 to calcium cyanamide in the presence of 10% calcium chloride at 700 °C.
Sciencemadness Discussion Board - Calcium cyanamide
2010/03/08 · Calcium cyanamide is produced on an industrial scale by fixation of atmospheric nitrogen by calcium carbide at temperatures above 1000C in electric furnaces: CaC2 + N2 → CaCN2 + C Other methods of preparation include: action of ammonia on cyanogen chloride, melting of urea with metallic sodium, high temperature reaction of hydrocyanic acid with calcium oxide and thermal decomposition …

Nitrogen fixation - Wikipedia
In 1898 Frank and Caro decoupled the process and produced calcium carbide and in a subsequent step reacted it with nitrogen to calcium cyanamide. The Ostwald process for the production of nitric acid was discovered in 1902. The Frank-Caro and Ostwald processes dominated industrial fixation until the discovery of the Haber process in 1909.
