The chemical formula is CON2H4, (NH2)2CO or CN2H4O, the molecular weight is 60, and the international non-proprietary name is Carbamide. The appearance is white crystals or powder. It is a product of animal protein metabolism and is commonly used as a nitrogen fertilizer for plants. Urea is synthesized in the liver and is a nitrogenous metabolite excreted by mammals. This metabolic process is called the urea cycle. Urea is the first organic compound obtained by artificially synthesizing inorganic substances. The chemical formula is as follows: CO (NH2)2 with molecular mass of 60.06, CO (NH2)2 is colorless or white needle-like or rod-like crystal, and industrial or agricultural products are white reddish solid particles without odor and taste. The nitrogen content is about 46.67%. The density was 1.335g/cm 3. Melting point 132.7 ℃. It is soluble in water and alcohol, and insoluble in diethyl ether and chloroform. Is alkalescent. Urea is easy to dissolve in water, 105 g of urea can be dissolved in 100 ml of water at the temperature of 20 ℃, and the water solution is in a neutral reaction. There are two types of urea products. The crystal urea is white needle-like or prism-like crystal form and has strong hygroscopicity. The granular urea is semitransparent particles with the particle size of 1-2 mm, the appearance is smooth, and the moisture absorption is obviously improved. The critical moisture absorption point is 80% relative humidity at 20 ℃, but the critical moisture absorption point is reduced to 72.5% at 30 ℃, so that the urea is prevented from being stored in an open manner in a humid climate in midsummer. At present, hydrophobic substances such as paraffin and the like are added in the urea production, and the hygroscopicity of the urea is greatly reduced.
