| 释义 | 硝酸钾 Another example of salt is potassium nitrate, KNO, a colorless solid which, mixed with charcoal a little sulfur, makes gunpowder. And ammonia had effective selectivity for the separation of potassium nitrate. This article described the principle and the processes on the preparation of potassium nitrate from ammonium nitrate and potassium chloride. Traditional manufacture of potassium nitrate with double decomposition was small scale and high energy cost. The computer simulation was performed in the potassium nitrate electrolyte solution using molecular dynamics method. Ammonium nitrate and potassium chloride are mainly used as raw materials for the production of agriculture- grade potassium nitrate by double decomposition method. Based on the technology requirements of potassium nitrate production and the properties of materials, a plate heat exchanger was designed for cooling and heat exchange. Gunpowder is composed of sulfur, carbon, and potassium nitrate. This paper introduces the analytical method of determining the contents of main components of potassium nitrate and powdered boron in BNP. The method, technological flowsheet, product quality, consumption quota of raw materials and project investment estimation of potassium nitrate production with new extractant is introduced. Agricultural nitre is one of the high performance chemical fertilizers for developing high performance and fine agriculture at home. A new cleaner technology for making chromium trioxide and potassium nitrate simultaneously by using nitric acid to decompose potassium dichromate has been brought forward. Through the test, the domestic KCl is purified by chemical precipitation process and can be met the requirement for the production of agriculture-grade potassium nitrate. The potassium nitrate products of our country have broad application prospects in the industry and agriculture and have great market potential. Describes the current situation of China's nitric acid and potassium nitrate production. Known as saltpeter, nitrite, a white opaque crystalloid like salt, is consisted of Sodium nitrite and potassium nitrite. A kind of black or brown explosives, the potassium nitrate, charcoal and sulfur mechanical mixture. To determine the effects of over- heating the Potassium Nitrate- Sorbitol mixture. Agricultural potassium nitrate and ammonium chloride are produced by double decomposition from potassium chloride and ammonium nitrate. That is because nitrates can react with proteins to form chemicals that cause cancer in laboratory animals. The principle of crystallization technology by cooling in vacuum during production of potassium nitrate was described. The technology for producing potassium nitrate was discussed and compared with potassium sulfate economically. It is valuable that using potassium nitrate to replace potassium sulfate. The chloride-free potash fertilizer include potassium sulphate, potassium nitrate, potassium dihydrogen phosphate and so on. Nitrate is added to most cured meats, However, the Food and Drug Administration limits the amounts. |
