I would like to ask the bosses who are engaged in chemical fertilizers, what is ammonium nitrate phosphate?

It should be compound fertilizer, the process is simple and easy to mix??????

Ammonium nitrate? The first time I heard about it, it was probably a clerical error from ammonium nitrophosphate. This is a compound fertilizer (also divided into monoammonium and diammonium). This is not a simple mixture as mentioned in #2. A simple mixture is called mixed fertilizer (personally, I feel that mixed fertilizer is to deceive farmers who do not know chemical knowledge).

Strictly speaking, from the perspective of chemical substances, ammonium nitrate phosphate is not a substance, as introduced by Haiyou upstairs: It is a kind of compound fertilizer, that is, nitrogen fertilizer and phosphorus fertilizer are mixed together in a certain proportion. From the perspective of chemical substances, it is strictly a mixture. As for the production process, it is actually very simple.: Mixing, melting, granulating, and finally the finished product is obtained. 1# hkykx

They should all be the same, they are just termed differently, they are all collectively called nitric acid phosphate fertilizer: Development of Nitrophosphate Fertilizers in the World Nitrophosphate fertilizers have been developed for less than a hundred years. In 1908, Russian scholars first proposed the rationality of the nitric acid phosphate fertilizer process. After the 1920s, Germany first produced nitric acid phosphate fertilizer. In 1928, Orin Johnson of the Norwegian Oda Company successfully developed a freezing method (called the Oda method). On this basis, many improved processes have emerged, such as the Norwegian NORSK HYDRO process, the Dutch STAMICARBON process, and the German HOECHST-UHDE process. In the early 1950s, affected by the shortage of sulfur resources in the world, France launched the PEC mixed acid method and carbonization method. Due to its simple process, it was quickly promoted around the world and many production devices were built. In the 1960s, with the further shortage of sulfur resources in the world and the further expansion of ammonia synthesis plants, the cost of synthetic ammonia dropped significantly, which promoted ammonia consumption and the development of nitric acid phosphate fertilizers. At this time, the nitric acid phosphate fertilizer industry was no longer satisfied with manufacturing products with low concentration and low water solubility. It began to develop products with high concentration and high water solubility to meet agricultural requirements. As a result, the NORSK HYDRO deep freezing process, the Czech direct freezing process, the ammonium sulfate recycling method and the solvent extraction method appeared, and they developed towards large-scale production. More than 1 million t/a nitric acid phosphate fertilizer plants supporting the 300,000 t/a ammonia synthesis unit have been put into production one after another, marking the maturity of nitric acid phosphate fertilizer technology and good economic benefits. According to statistics, there were only 50 nitric acid and phosphate fertilizer plants built in the 1950s. In the 1970s, 22 more plants were built, and now there are more than 100 plants. In the 1960s, the statistical production capacity was about 10 million tons (in kind), and now it has reached 30 to 40 million tons (in kind), accounting for 10% to 15% of the world's fertilizer production. Judging from the areas where factories were built, they were mainly concentrated in Europe. In the late 1970s, many in Asia * * Nitrophosphate fertilizer production plants have also been built one after another. Therefore, in areas lacking sulfur resources and rich in phosphate ores, * * , Nitrophosphate fertilizer is one of the ways to develop compound fertilizer. The Development and Current Situation of Nitrophosphate Fertilizer in my country Domestic research work began in the late 1950s. The Shanghai Research Institute of Chemical Industry has conducted extensive research on carbonization method, mixed acid method, freezing method, sulfate method and solvent extraction method. Due to various reasons, especially the influence of phosphate rock quality, only a small part of the research work has been expanded to the pilot stage. In addition, the Nanjing Institute of Chemistry and Chengdu University of Science and Technology have carried out corresponding research work. In May 1976, Nanhua Company built a 3000t/a indirect freezing method intermediate test device, and it was officially put into testing by the end of 1977. Since then, the Shanghai Research Institute of Chemical Industry has also established an intercooling method prototype test device to evaluate the freezing process of various phosphate ores and conduct some basic research on the freezing process. In September 1987, the Shanxi Fertilizer Factory (Shanxi Tianji Group), which introduced the Norwegian NORSK HYDRO process, was completed and put into operation, ending the history of my country's nitric acid-free phosphate fertilizer production plants. Subsequently, the Kaifeng Fertilizer Factory's nitric acid phosphate fertilizer production workshop using the nitric acid-sulfuric acid mixed acid process was completed and put into operation.

"Compound fertilizer: It is divided into chlorine-based compound fertilizer, sulfur-based compound fertilizer and nitro-based compound fertilizer. " Just to add: Are there any urine-based compound fertilizers? ? Could the experts please introduce the Haqi process? Thank you!

Molecular formula: CAS number: nature: * A mixture of anhydrous acid and ammonium phosphate. Representative products include: (1) Containing 25% nitrogen and 25% phosphorus pentoxide ； (2) Containing 28% nitrogen and 14% phosphorus pentoxide ； (3) Containing 30% nitrogen and 10% phosphorus pentoxide ； (4) Add potassium salt to make it an ammonium nitrate potassium fertilizer containing 17% nitrogen, 17% phosphorus pentoxide, and 17% potassium oxide. There are two ways to make it: (1) Produced by the neutralization reaction of nitric acid, phosphoric acid and ammonia ； (2) Directly use nitric acid to decompose phosphate rock, and then remove calcium nitrate to prepare a nitrate-phosphate compound fertilizer, the main component of which is ammonium nitrate. In Europe most of the product is used as fertilizer.
