CARBON MONOXIDE CAS# 630-08-0

chemical industry,In the chemical industry, carbon monoxide is the basis of one-carbon chemistry. [2] As the main component of syngas and various types of coal gas, carbon monoxide is an important raw material for the synthesis of a series of basic organic chemical products and intermediates, starting from carbon monoxide, almost all basic chemicals can be prepared, such as ammonia, phosgene and alcohols, acids, anhydrides, esters, aldehydes, ethers, amines, alkanes and olefins. At the same time, the use of carbon monoxide and transition metal reaction to generate carbonyl metal or carbonyl metal derivatives of the properties, can be prepared organic chemical production of various types of homogeneous reaction catalysts. [25] [40] Besides, carbon monoxide can be used as a terminator in polyethylene polymerization reactions.Metallurgical industry,In the metallurgical industry, using the thermal decomposition reaction of carbonylated metals, carbon monoxide can be used to extract high-purity nickel from raw ore, and can also be used to obtain high-purity powder metals (such as zinc white pigments) and produce certain high-purity metal films (such as tungsten film and molybdenum film, etc.). At the same time, carbon monoxide can be used as a reducing agent for refining metals [2], such as oxides used to reduce iron in steelmaking blast furnaces (for the equation see “Physicochemical properties and chemical properties”); In the production of polycrystalline diamond films, research-grade carbon monoxide (≥99.99%) can be used to provide a carbon source for the chemical vapor deposition process. Also, a mixture of carbon monoxide and hydrogen (syngas) can be used to produce certain special steels, such as reduced iron ore to produce sponge ironIn addition to both the chemical and metallurgical industries, carbon monoxide can be used as a fuel [2], while high-purity carbon monoxide is used as a standard gas, carbon monoxide laser, environmental monitoring and scientific research. Among them, carbon monoxide standard gas can be applied to the calibration and detection of petrochemical process control instruments, the control of petrochemical product quality, environmental pollutant detection, automobile exhaust emission detection, the calibration of mine alarms, the detection of various factory exhaust gases, medical instrument calibration, power system transformer oil quality testing, air separation product quality control, traffic safety testing instrument calibration, geological exploration and seismic monitoring, metallurgical analysis, gas appliance experiments and calorific value analysis, fertilizer industry instrument calibration, etc. Also, carbon monoxide is often used for the preservation of fish, meat, fruits and vegetables and bagged rice, especially the preservation of sashimi, and is used as a color fixative because it can make the meat texture rosy.
