Urea Powder Usage and Synthesis.

Urea is a chemical used in a wide range of applications. In the dyeing industry, urea improves the color fixation of cellulosic fibers and also lowers the melting point of dyes, alkalis and anti-swimming agents, thus facilitating the adsorption and diffusion of dyes.

In agriculture, urea is a highly concentrated nitrogen fertilizer that can be used to produce a variety of compound fertilizers and as feed for ruminants.

However, there are certain risks associated with the use of urea, such as toxic effects if fed above a certain level, and symptoms of toxicity such as restlessness, salivation, muscle tremors, etc., may occur 30 minutes after overfeeding.

Uses of Urea.

Urea is mainly used as fertilizer. It is also used as a raw material for manufacturing urea-formaldehyde resin, polyurethane and melamine-formaldehyde resin, and has a wide range of applications in medicine, explosives, tanning, flotation agents, pigments and petroleum products dewaxing. When urea is heated to 200℃, solid cyanuric acid is generated.

Derivatives of cyanuric acid trichloroisocyanuric acid, sodium dichloroisocyanate, isocyanuric acid three (2-hydroxyethyl), isocyanuric acid three (allyl) ester, three (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanate, isocyanuric acid triglycidyl ether, cyanuric acid, cyanuric acid, such as melamine complexes, have many important applications. The first two are new high-grade disinfectant and bleaching agent, and the total production capacity of trichloroisocyanuric acid is more than 80,000 tons worldwide.

Urea is an important raw material for the production of pesticides, which can produce fungicides such as cymoxanil and ethylpyrimidinol, insecticides such as triazophos, vinclozolin, pyrimethanil, fenitrothion, aminopyralid and herbicides such as cycloheximide.

Characteristic of Urea.

Urea, also known as urea or carbamide, is a final product of protein metabolism in humans and mammals, and a major organic nitrogen compounds excreted by the animal body. Pure product is white granular or needle-like, prismatic crystals, mixed with iron and other heavy metals is light red or yellow. Tasteless and odorless, soluble in water, ethanol and benzene, insoluble in ether and chloroform.

At 20℃, 100kg of water can dissolve 105kg of urea, and absorb heat when dissolved. The aqueous solution is neutral reaction. The nitrogen content of the pure product is 46.65%, agricultural urea is 42% to 46%, containing a small amount of diureas, generally less than 2%, usually harmless to crop growth; urea specific gravity and capacity are small, each cubic meter of fertilizer weighs 0.65 tons.

Product Method of Bulk Urea Powder.

Urea, the end product of protein metabolism in mammals, was industrially produced in Germany in 1922 by synthesizing urea from ammonia and carbon dioxide. Ammonia reacts with carbon dioxide to form amyl carbamate, which is then dehydrated to form urea.
