It is used as raw material for fertilizer, animal feed, explosive, stabilizer and urea formaldehyde resin.
Urea is an important raw material for pesticide production. It can produce fungicides such as cyanamide cream, ethylpyriphenolate, insecticides such as triazophosphoron, flufenethion, pyrimidine oxyphosphorus, pyridinitrile, permethrin, herbicide chloroxone, etc.
Agricultural use as nitrogen fertilizer, industrial use as feed additive, used in the manufacture of explosives, stabilizer and urea formaldehyde resin.
It is a crop fertilizer used to improve the efficiency of nitrogen in urea.
Yeast feed; Gumdrop tissue improver. GB2760-90 is listed as a processing aid. Used for alcoholic beverages, gelatin products, wine, yeast baking products.
Urea is mainly used as a fertilizer. In industry, it is also used as a raw material for the manufacture of urea-formaldehyde resin, polyurethane and melamine-formaldehyde resin. It is also widely used in medicine, explosives, leather, flotation agent, pigment and dewaxing of petroleum products. Urea is heated to 200ºC to form solid trichloric acid (cyanuric acid). The derivatives of cyanuric acid, trichloroisocy anuric acid, sodium dichloroischemicalbook cyanate, tri (2-hydroxyethyl) isocyanuric acid, tri (allyl) isocyanuric acid, tri (3, 5-di-tert-butyl-4-hydroxy-benzyl) isocyanate, tridiglycidyl isocyanate, cyanuric acid melamine complex, etc., have many important applications. The first two are new high-grade disinfection, bleach, trichl oroisocyanuric acid worldwide total production capacity of more than 80,000 t.
Test for antimony and tin in analysis. Determination of lead, calcium, copper, galli um, phosphorus, iodide and nitrate. Serum Chemicalbook bilirubin was measured with standard solution when blood urea nitrogen was determined. Separation of hydrocarbons. The oxides and nitrous acids used to decompose nitrogen in analysis. Prepare the medium. Fring method when determining uric acid stabilizer, homogeneous precipitation.
