Description
Предметом игюто щего изобретени вл етс способ получени неслсжнваюшейс иммиачной селитры путем введени в ее раствор пытнжкн, полученной от разложепи фосфорита азотной кислотой.The subject of the present invention is a process for the preparation of uncomplicated immacy nitrate by introducing into its solution a test obtained from the decomposition of phosphate by nitric acid.
Согласно изобретению процесс осуществл ют следующим образом.According to the invention, the process is carried out as follows.
Снмчлла фосфорит разлагают Г)П -55%-ной азотной кислотой. Отделенную от неристворившегос осадка (песка) выт жку добавл ют в раствор аммиачной селитры в колнчестве , обеспечиваюп1,ем содержание в готовом продукте от 0,5 до 2,5% РЛ.-..Snmcall phosphorite decompose G) P -55% nitric acid. Separated from an undissolved sediment (sand), the extract is added to a solution of ammonium nitrate in a mixture, ensuring that the content in the finished product varies from 0.5 to 2.5% of X-ray radiation.
Добавка выт жки может быть осупхествлена по трем вариантам;The addition of stretching can be opscale in three options;
1)введение выт жки в кислые щелока аммиачной селитры с последующей нейтрализацией полученного раствора аммиаком, а также выпаркой , кристаллизацией и сушкой 110луче1Н1ого продукта;1) introducing the extract into the acidic liquor of ammonium nitrate, followed by neutralization of the resulting solution with ammonia, as well as evaporation, crystallization, and drying of the 1H1 product;
2)добавка выт жки к азотной кис.1оте с последующей переработкой полученной смеси в аммиачную селитру обычными приемами;2) addition of the extract to nitric acid with the subsequent processing of the mixture into ammonium nitrate by usual methods;
3)нейтрализаци фосфориокислотпой выт л ки в отдельном аппарате газообразным аммиаком до кнслотиости около 20 , добавка полученного продукта к кислым щелокам амми 1чной селптры с последующей дополнительной нейтрализацией всей смеси аммиаком, а также выпаркой, кристаллизацией и cyniкой аммиачной селитры.3) neutralizing the phosphoric acid extract in a separate apparatus with gaseous ammonia to approximately 20, adding the resulting product to the acidic lye of the ammonia salt of the mixture, followed by further neutralization of the entire mixture with ammonia, as well as evaporation, crystallization and synthesis of ammonium nitrate.
Аммиачна . селитра, получепна описаи1гым способом, не слеживаетс П) длительном хранении;Ammonia. nitrate, which is obtained in a descriptive manner, does not spy P) for long-term storage;
Предмет изобретени Subject invention
Способ по.пученн неслежипающейс аммиачной селитры путем добавки к ней вегцества, предохран юн1его ее от слеживани , о т л нч а ю HI, и и с тем, что в качестве указа1П ой добавки в раствор аммиачной селитры ввод т выт жку, полученную от раз.гтоженн фосфорита азотной кислотой из расчета получени в аммиачной селитре от 0,5 до 2,5% PS OR, носле чего раствор нейтрализуют аммиаком, упаривают , кристаллизуют и cyinaT известпыми приемами./.The method according to the method of cracking the ammonium nitrate by adding vegetation to it, preventing it from caking, about one day, and with the fact that, as an indication of the additive, ammonia nitrate is injected into the extract obtained from the equivalent of phosphorus with nitric acid at the rate of obtaining in ammonium nitrate from 0.5 to 2.5% of PS OR, while the solution is neutralized with ammonia, evaporated, crystallized, and cyinaT by limescale techniques.
