Physical & Chemical Property:
Urea, also known as urea or carbamide, is an end product of protein metabolism in humans and mammals, and is also a major organic nitride excreted by animals. Pure products are white granular or acicular, prismatic crystals, mixed with iron and other heavy metals are light red or yellow. Tasteless and odorless, soluble in water, ethanol and benzene, insoluble in ether and chloroform. At 0℃, 100 kg of water can dissolve 105 kg of urea, which absorbs heat when dissolved. The aqueous solution is neutral. The nitrogen content of pure products is 46.65%, agricultural urea is 42% ~ 46%, containing a small amount of biuret, generally less than 2%, usually harmless to crop growth; The specific gravity and bulk weight of urea are small, 0.65 tons per cubic meter of fertilizer.
Application:
Urea is an important raw material for pesticide production, which can produce fungicides such as urethane and ethylphenuron, insecticides such as triazophos, phoxophos, pyrimidine, pyridinitrile, permethrin, and herbicides such as chlorfenoxon.
