Urea is composed of carbon, nitrogen, oxygen and hydrogen organic compound, also known as urea (urine). The chemical formula for CON2H4, (NH2) 2 co or CN2H4O, molecular mass, 60 international generic name is Carbamide. Appearance is white crystal or powder. It is a product of animal protein metabolism, is often used as a nitrogen fertilizer plants. Urea synthesis in the liver, are mammals excrete nitrogen metabolites in vivo. The metabolic process known as urea cycle. Urea is the first to synthetic inorganic material and organic compounds. Vitalism ousted from now on.
Generates salt and acid. Hydrolysis. Can be carried out under high temperature condensation reaction, producing biuret, three urea and cyanuric acid. Heated to 160 ºC decomposition, to produce ammonia at the same time into cyanate. Because contain the substance in human urine, so named urea. 46% of urea nitrogen (N), is a solid nitrogen fertilizer nitrogen content in the highest.
Urea under the action of acid, alkali, enzyme hydrolysis (acid, alkali heating) can generate ammonia and carbon dioxide.
On the thermal instability, heating to 150 ~ 160 ºC deamination into biuret. If the rapid heating deamination and melamine into six-member ring compound cyanuric acid.
And acetyl chloride or acetic anhydride can generate acetyl urea and diacetyl urea.
Under the effect of sodium ethylate and diethyl malonate reaction between propylene ureide (also called barbituric acid, because its have certain acid).
In ammonia, etc. Under the action of alkaline catalyst can react with formaldehyde, condensed into urea-formaldehyde resin.
Generate semicarbazide with hydrazine hydrate.
Urea soluble in water, 100 ml at 20 ºC water soluble 105 grams, aqueous solution was neutral reaction. There are two kinds of urea product. Crystallization of urea with a white acicular or prismatic crystal shape, moisture absorption is strong. Granular urea translucent particles for particle size of 1 ~ 2 mm, smooth appearance, hygroscopic property have improved significantly. 20 ºC, relative humidity 80% critical moisture absorption points but 30 ºC, the critical moisture absorption points to 72.5%, so the urea to avoid open storage under humid climate in the summer. Now add hydrophobic material such as paraffin in urea production, its hygroscopicity.
