TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The method comprises: reacting the metal cyanamide, together with any unreacted metal carbide, with water to decompose the metal carbide into acetylene and acetylene-related compounds and metal hydroxide; combusting the acetylene and acetylene-related compounds to release energy; separating the metal cyanamide and the metal hydroxide for recycling in the production process; and reacting the metal cyanamide with carbon dioxide and water in acidic solution to form hydrogen cyanamide and calcium carbonate, separating the hydrogen cyanamide, reacting the hydrogen cyanamide in basic solution to form cyanoguanidine, and separating the cyanoguanidine for use in the composition; and introducing the nitrogen so that it passes through the metal carbide. The reaction of the metal oxide and the source of carbon occur: in an arc reactor which is a rotating arc reactor at 1100-2200 degrees C, preferably 2000 degrees C; or in the presence of calcium fluoride. The reaction occurs in a reactor, and the metal carbide is formed in a first section of the reactor, and in a second section of the reactor the hot metal carbide product is contacted with nitrogen to form the metal cyanamide. The metal cyanamide is cooled and collected in a third section of the reactor. The metal carbide is maintained in a fluidized state. Preferred Components: The metal oxide is calcium oxide or magnesium oxide. The source of carbon is methane, hydrocarbon fuel, coal or charcoal. The weight of cyanoguanidine in the composition is equal to 10-100 wt.% of the composition. EXAMPLE - A mixture of methane gas and entrained calcium oxide particles, in the molar ratio of 3:1 was fed continuously to a tubular reaction chamber, maintained at 2000 degrees C by the presence of a rotating electric arc. Magnetic coils surround the reaction chamber and maintain a magnetic field of 120 gauss within the reaction chamber to rapidly rotate the arc. The cathode was a 0.25 graphite rod held in the center of a cylindrical graphite anode with a 0.5 inside diameter. The arc was powered by a power supply of the type used for arc-welding with a maximum output voltage of 160 V. The arc was started in argon gas and once established the gas flow was switched to methane and the vibratory feeder supplying the calcium oxide started. The arc power level was 25 kW. The calcium oxide particles were in the size of 44-75 mu m. Then, calcium fluoride (1%) was added to the calcium oxide to facilitate the subsequent reaction of the calcium carbide with nitrogen gas. The methane flow rate was 16 l/minute. The reaction chamber of 1 inside diameter was fabricated from a suitable high temperature refractory material able to withstand high temperature reducing environments. Under these conditions 70-90% of the calcium oxide was converted to calcium carbide with a particle size of 0.3 mu m. The particulate calcium carbide was allowed to cool to 1000 degrees C before entering through a valve the region of the reaction chamber containing the nitrogen gas. The nitrogen gas purity was higher than 99.9%. The flow rate of the nitrogen was adjusted to 0.5-2.5 l/minute to maintain the calcium carbide in a fluidized state. The nitrogen gas enters through a fritted quartz plate at the bottom of the reaction chamber. After a period of 8 minutes the flow of nitrogen was stopped and the product calcium cyanamide together with some unreacted calcium carbide was removed from the reactor. After cooling, the product (10 g) was stirred with water (40 g) to form a slurry. After the release of acetylene gas stops, the solution was cooled to 20 degrees C and carbon dioxide (10 g) was bubbled into the slurry with stirring over a period of 8 hours. The insoluble material was removed by filtering and the solution evaporated to dryness at 80 degrees C to yield cyanoguanidine (6-8 g).
