【 Molecular Formula 】 H3PO4.CO (NH2) 2
【 Molecular Weight 】 158.0
【 Execution Standard 】 Q/62089823-7.3-2002
[Property] The appearance is white granular crystals, which are highly soluble in water and insoluble in organic solvents. The melting point is 117.3 ℃, and the aqueous solution is strongly acidic. The pH value of a 1% aqueous solution is 1.6-2.4. Low thermal stability, prone to decomposition reactions when heated.
【 Purpose 】 Urea phosphate provides two elements, phosphorus and non protein nitrogen (urea nitrogen), with higher safety than urea It is also a high concentration nitrogen phosphorus compound fertilizer (with a total nutrient element N+P2O5 of 61%), suitable for alkaline soils In addition to being used as a fertilizer, it can also be used as a flame retardant, metal surface treatment agent, cleaning agent, and auxiliary agent for purifying phosphoric acid.
