| Overview | Urea nitrate is the reaction product of urea and nitric acid. It is a white or colorless crystalline solid, slightly soluble in water and ethanol, and insoluble in nitric acid, ether, Benzene, chloroform, in case of high heat or collision, there is a risk of combustion and explosion. It is mixed with organic matter, reducing agent, sulfur, phosphorus, etc. to form an explosive mixture; mainly used in the manufacture of explosives and organic synthesis intermediates. |
| preparation method | 1.5.5mol/L nitric acid is reacted with urea (I .e. 100g of urea, 135g of nitric acid and 215g of water) at a reaction temperature of 20 ℃ for 20min and filtered. 2.5.5mol/L nitric acid is reacted with urea (I. e. 100g of urea, 135g of nitric acid and 215g of water) at a reaction temperature of 70 ℃ for 20min and filtered. 3.100g urea, 150mL water, stirring and dissolving for 15min, adding 189g nitric acid, reaction temperature 40 ℃, reaction 60min, filtration. |
| application | used to make explosives and organic synthesis intermediates. Used in the production of carbamate products, oil field tertiary oil recovery plugging removal acidifier. (2015-11-04) |
| storage method | store in a cool, dry and ventilated warehouse for explosives. The storage temperature shall not exceed 32 ℃ and the relative humidity shall not exceed 80%. If water is used as a stabilizer, the storage temperature shall not be lower than 1 ℃ and the relative humidity shall be less than 80%. Stay away from fire and heat sources. The package is sealed. Should be stored separately from oxidants, easy (combustible) materials, etc., avoid mixed storage. Explosion-proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are prone to spark. The storage area shall be equipped with suitable materials to contain leaks. Vibration, impact and friction are prohibited. |
| use | used to produce urethane products, oil field tertiary oil recovery plugging removal acidifier |
| category | oxidant |
| toxicity classification | poisoning |
| acute toxicity | reference value oral-mouse LD50: 1028 mg/kg |
| explosive hazard characteristics | can be exploded when mixed with reducing agent, sulfur, phosphorus, etc.; it can be exploded when heated and impacted |
| flammability hazard characteristics | high heat and combustible; combustion produces toxic nitrogen oxide smoke |
