Nitrogen dioxide (NO2) is a brown-red, highly active gaseous substance. Nitrogen oxides are the general term for nitric oxide, nitrogen dioxide and other nitrogen oxides, and nitrogen dioxide plays an important role in the formation of ozone. Man-made nitrogen dioxide mainly from the release of high-temperature combustion process, such as motor vehicles, power plant emissions and so on. Household stoves and gas burners also generate considerable amounts of nitrogen dioxide
Short-term exposure (eg, less than 3 hours) can lead to an allergic reaction to respiratory illnesses, impair lung function, and increase the incidence of respiratory diseases in children and adolescents (5-12 years). In addition, nitrogen dioxide is one of the causes of acid rain. In fact, the environmental effects of nitrogen dioxide are diverse, including the effects of changes in competition and composition between wetland and terrestrial plant species, reduced atmospheric visibility, acidification of surface water, eutrophication Rich in nutrients such as nitrogen and phosphorus algae multiply and lead to hypoxia) and increase in water harmful to fish and other aquatic toxins.
Store in a cool, ventilated warehouse. Away from the fire, heat source. The temperature should not exceed 30 DEG C. Should be separated from the easy (but) fuel, halogen, food chemicals storage, avoid by all means. The storage area should be equipped with emergency treatment equipment.
Used as an oxidizing agent in chemical reaction and rocket fuel, used as a catalyst in the production of sulfuric acid in nitroso process.
NO2 is used as an intermediate in the manufacturing of nitric acid, as a nitrating agent in manufacturing of chemical explosives, as a polymerization inhibitor for acrylates, and as a flour bleaching agent.
It is also used as an oxidizer in rocket fuel, for example in red fuming nitric acid; it was used in the Titan rockets, to launch Project Gemini, in the maneuvering thrusters of the Space Shuttle, and in unmanned space probes sent to various planets
