Technical field
The present invention relates to synthesis ammonia chemical production field, specifically a kind of green high-efficient organic synthesis urea fertilizers.
Background technique
The chemical name of urea is carbonyl diamide, and molecular formula is CO (NH2) 2, molecular weight 60.06, and nitrogen content is
46.65%, it is the highest solid nitrogenous fertilizer of nitrogen content.Because containing this substance in the urine of the mankind and mammal, urea is
Colourless, tasteless, odorless needle-shaped or prismatic crystallization.At a temperature of 20-40 degree, the specific gravity of crystal is 1.335 grams/cm3, urea
Soluble easily in water and ammonia also is soluble in alcohol, and packaging and storage are it is noted that moisture-proof.Urea is mainly used as fertilizer, feed and the raw material of industry.?
Industrial synthesis material of the urea as high polymer, for producing plastics, coating and binder, is urinated for formaldehyde resin is made
Element is also used for the departments such as medicine, process hides, pigment.
However, current synthesis ammonia and preparation production technology still has much room for improvement, cost is very high, big to soil harm, produces
Raw pollution is big, and generally big to environmental hazard and not high for the urea synthesis fertilizer purity of production in the prior art, quality is not
Height, it is low containing production efficiency, it is not able to satisfy the market demand, it is anxious to be modified.
