Product Introduction:

Carbamide Urea, also known as urea and carbonamide, has the chemical formula CH4N2O. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is white crystals (small balls). It is one of the simplest organic compounds and the main nitrogen-containing end product of protein metabolism and decomposition in mammals and certain fish.

Carbamide Urea is a neutral fertilizer suitable for a variety of soils and plants. It is a chemical nitrogen fertilizer that is convenient to store, easy to use, less harmful to the soil, and large in dosage. It is the nitrogen fertilizer with the highest nitrogen content. In industry, ammonia and carbon dioxide are used to synthesize Carbamide Urea under certain conditions.

Product physical properties:

Carbamide Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20℃. The aqueous solution showed a neutral reaction.

There are two types of Carbamide Urea products. Crystalline urea has strong hygroscopicity, showing white needle-like or prismatic crystals, and agglomerates after absorbing moisture. The moisture absorption speed is 12 times faster than that of granular urea.

Uric acid particles are semi-transparent particles with a particle size of 1-2mm, smooth appearance and greatly improved hygroscopicity. At 20°C, the critical moisture point is 80% relative humidity, but at 30°C, the critical moisture point drops to 72.5%, so Urea Powder should not be stored in humid climates in midsummer.

Adding hydrophobic substances, such as paraffin wax, to the production of Carbamide Urea can significantly reduce the hygroscopicity.

The chemical properties of Carbamide Urea:

  • Carbamide Urea can react with acids to form salts. There is hydrolysis. The condensation reaction can be carried out at high temperature to generate biuret, triurea and cyanuric acid. When heated to 160°C, it decomposes to generate ammonia gas and simultaneously generates isocyanic acid. This substance is called Carbamide Urea because it is contained in human urine. Urea Powder contains 46% nitrogen (N), the highest nitrogen content of all solid nitrogen fertilizers.

  • Urea Powder can be hydrolyzed to produce ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali must be heated).

  • Heating is unstable, heating to 150~160℃ deamidation into a burette. The reaction of copper sulfate with the burette is purple, which can be used to identify elements. After rapid heating, deaminated and trimerized into six-membered ring compound cyanuric acid. [Mechanism of action: Deaminated first generates isocyanic acid (HN=C=O), and then generates trimer. ]

  • Acetyl chloride or acetic anhydride can be used to produce acetyl urea and diacetyl urea.

  • Carbamide Urea reacts with diethyl malonate under the action of sodium ethoxide to form malonyl urea (also known as barbituric acid because of its acidity).

  • Carbamide Urea can react with formaldehyde to form urea-formaldehyde resin under the action of alkaline catalysts such as ammonia and polycondensate.

  • Reacts with hydrazine hydrate to generate semicarbazide.
