Urea-phosphoricacid - Nature
Open Data Verified Data
colorless transparent prismatic crystals. It has a parallel layered structure, and the layers are connected by hydrogen bonds, which belongs to orthorhombic crystal system. It is a phosphoric acid double salt with an amino structure. N content 17. 73%; P content 19. 59%. Melting Point 117~117.5 deg C; Density 1.74g/cm3. The crystal is soluble in water and ethanol, insoluble in ethers, toluene, carbon tetrachloride, etc. The aqueous solution is acidic, and the pH value of the 1% aqueous solution is 1.89. The solubility at 46 °c was 202g/L. The amino structure of Urea phosphate determines that Urea phosphate has a small thermal stability, which is easy to decompose, and the decomposition products are not the same at different temperatures. The thermal decomposition rate increases with the increase of temperature. Urea phosphate dissolved in water after the decomposition of urea and phosphoric acid, and release a small amount of carbon dioxide and ammonia.

Urea-phosphoricacid - Preparation Method
Open Data Verified Data
The synthesis process of Urea phosphate can be divided into wet process phosphoric acid method, thermal phosphoric acid method and polyphosphoric acid method. In the industrial production of Urea phosphate in China, the thermal phosphoric acid method is generally used, that is, the thermal phosphoric acid and urea are added into the reactor, and the urea is dissolved in phosphoric acid at a certain temperature. After the reaction is completed, the crystalline Urea phosphate is obtained, and then dehydrated, urea phosphate was obtained by drying.

Urea-phosphoricacid - Use
Open Data Verified Data
Urea phosphate is a hormone-free feed additive for ruminants, which is a binary nutrient of nitrogen and phosphorus. It can provide livestock with phosphorus and non-protein nitrogen, which can slow down the release and transmission rate of nitrogen in the stomach tumor and blood of cattle and sheep, and is especially suitable for ruminant feed. Used as livestock feed additive, Urea phosphate can increase the content of acetic acid and propionic acid in the stomach of livestock and enhance the activity of dehydrogenase, promote the physiological metabolism of cattle and sheep and the absorption and utilization of nitrogen, phosphorus and calcium, it is an important feed additive for non protein nitrogen and nutrient element phosphorus. On cattle, sheep have obvious weight gain, increase milk effect, has a good antiseptic effect on silage. In addition, Urea phosphate aqueous solution shows a certain degree of acidity, can regulate the acidity of the animal stomach. As a feed additive, Urea phosphate is easy to be absorbed and utilized by animals, and has a good effect on the physiological metabolism of ruminants. The safety is higher than that of urea, and it is convenient to use. Therefore, Urea phosphate is a safe and excellent non-protein nitrogen and nutrient phosphorus important feed additives. Urea phosphate is also a high concentration of nitrogen and phosphorus compound fertilizer, suitable for alkaline soil, rice, wheat, rape and other crops have the effect of increasing yield. It is also used as a flame retardant, metal surface treatment agent, fermentation nutrient agent, cleaning agent and purifying phosphoric acid.

Urea-phosphoricacid - Reference Information
| LogP | -1.73 at 20℃ |
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Use | Used as feed additives for cattle, sheep, and horses ruminants, as well as flame retardants, metal surface treatment agents, cleaning agents, etc. It is an excellent feed additive, which can provide livestock with phosphorus and non-protein nitrogen (urea nitrogen) two nutrient elements, especially suitable for ruminant feeding, it can slow down the release and transmission of nitrogen in the rumen and blood of cattle and sheep, and is safer than urea. It is also a high-concentration nitrogen and phosphorus compound fertilizer, suitable for alkaline soil, and has an effect on increasing production of rice, wheat, rape and other crops. It is also used as flame retardant, metal surface treatment agent, fermentation nutrient agent, cleaning agent and auxiliary agent for purifying phosphoric acid. |
| production method | the urea solution containing 50% P2O5 wet process phosphoric acid and 60% (mass) is added to the mixing reactor by secondary crystallization method, mixed at 110 ℃, pumped into the vacuum evaporator for concentration, then centrifuged and dried to obtain urea phosphate finished product. In order to obtain feed grade products, secondary crystallization can be carried out. After separation, the mother liquor is concentrated and then returned to the mixing reactor for utilization. Its H3PO4 + CO(NH2)2 → H3PO4?CO(NH2)2 vacuum concentration one-step method to pretreat dilute phosphoric acid containing 25% P2O5 (containing 6% impurities) with caustic soda and decantation to remove sodium fluosilicate, and then add it to the batch reaction tank with molten urea, the batching ratio is 21g urea to 100g phosphoric acid solution. Under these conditions, urea phosphate is completely dissolved, then the dilute solution is preheated, and then it enters a vacuum concentrator (P<13.3 × 100 Pa) for concentration at 60 ℃. Then it is sent to the crystallizer to cool to 20 ℃ to precipitate crystallization. The slurry is decanted in the mother liquor clarification tank, and the product is washed and dried with a small amount of water to produce urea phosphate. Its H3PO4 + CO(NH2)2 → H3PO4?CO(NH2)2 |
