Description
Urea nitrate is a colorless crystalline compound that is formed by the neutralization of urea with nitric acid. It is slightly soluble in water and soluble in alcohol, with a melting point of 152°C. Urea nitrate is a dangerous fire and explosion risk, and it decomposes at 305.6°F (152°C). The compound is shipped with not less than 20% water by mass and has a four-digit UN identification number of 1357.
Uses
Used in Explosives Industry:
Urea nitrate is used as a sensitizer for explosives due to its ability to enhance the explosive properties of other materials. Its high reactivity and sensitivity to heat and shock make it a valuable component in the manufacturing of various explosive devices.
Used as a Fertilizer:
Urea nitrate is utilized as a fertilizer in the agricultural industry, providing essential nitrogen to promote plant growth. Its water-soluble properties allow for easy absorption by plants, making it an efficient source of nutrients for crops.
Used as an Organic Reagent:
In the chemical industry, urea nitrate is employed as an organic reagent in various chemical reactions. Its unique properties make it suitable for use in the synthesis of different compounds and materials.
Used in the Manufacture of Urethane:
Urea nitrate is also used in the production of urethane, a versatile polymer with a wide range of applications, including foams, elastomers, and coatings. Its role in the manufacturing process is crucial for the formation of the desired urethane products.
Air & Water Reactions
Easily ignited. Burns very vigorously to generate toxic oxides of nitrogen. Slightly soluble in water.
Reactivity Profile
UREA NITRATE is explosive when left in dry state. Wetting reduces possibility of explosion but may explode under prolonged exposure to heat or fire, even when wet. Urea nitrate reacts with strong oxidizer such as perclorates and hypochlorites. With hypochlorites Urea nitrate forms a compound nitrogen trichloride which explodes spontaneously in air (J. Am. Chem. Soc. 63:3530-32). Organic nitrates may explode when shocked, exposed to heat or flame or by spontaneous chemical reaction. Urea nitrate must be stored in a cool, ventilated place, away from acute fire hazards and easily oxidized materials. Also reacts violently with Al; BP; cyanides; esters; PN2H; P; NaCN; SnCl2; sodium hypophosphite; thiocyanates. Dangerous disaster hazard due to fire and explosion hazard. On decomposition, they emit toxic fumes. They are powerful oxidizing agents which may cause violent reaction with reducing materials. Nitrates should be protected carefully in storage. (SAX and Lewis, 1987) p.664. Decomposition is catalyzed by the presence of heavy metals such as lead or iron in trace amounts [Bretherick, 1995, pg. 201]. Produces toxic oxides of nitrogen during combustion. Decomposed with explosive evolution of gas during the evaporation of an alkaline solution. [Bretherick, 1995, p. 201].
Health Hazard
Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
Safety Profile
A mild irritant.
Flammable when exposed to heat or flame.
The dry nitrate may explode when heated.
The presence of heavy metals (e.g., lead,
iron) catalyzes the thermal decomposition of
urea nitrate. When heated to decomposition
it emits toxic fumes of NOx.
Purification Methods
Crystallise it from dilute HNO3 or EtOH (m 157-158o) and dry it in a vacuum over P2O5. [Beilstein 3 H 54, 3 I 25, 3 II 45, 3 III 105, 3 IV 94.]
Check Digit Verification of cas no
The CAS Registry Mumber 124-47-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124-47:
(5*1)+(4*2)+(3*4)+(2*4)+(1*7)=40
40 % 10 = 0
So 124-47-0 is a valid CAS Registry Number.
