Abstract
1. Композиция на основе нитрата карбамида, отличающаяся тем, что помимо нитрата карбамида композиция содержит влагу не более 4% и фосфорсодержащий компонент в количестве до 1% (в пересчете на ортофосфорную кислоту).2. Композиция по п.1, отличающаяся тем, что в качестве фосфорсодержащего компонента использовали такие соединения фосфора, как ортофосфорная кислота и ее замещенные производные, например оксиэтилидендифосфоновая кислота (ОЭДФК), нитрилотриметилфосфоновая кислота (НТФК), в т.ч. стехиометрически уравновешенные в композиции в виде соли, в частности в виде карбамидных солей (особенно, если это необходимо, чтобы фосфорсодержащий компонент перевести в твердофазное состояние).3. Способ получения композиции на основе нитрата карбамида и фосфорсодержащего компонента, отличающийся тем, что процесс получения композиции ведут в две стадии: на первой стадии из карбамида, азотной кислоты, фосфорсодержащего компонента и воды нарабатывают маточник, представляющий собой водный раствор карбамида, азотной кислоты и фосфорсодержащего компонента, содержащий не более 34% карбамида, не более 16% азотной кислоты и не более 6,3% фосфорсодержащего компонента; на второй стадии из карбамида, азотной кислоты и фосфорсодержащего компонента получают упомянутую композицию (содержащую, помимо нитрата карбамида, влагу не более 4% и фосфорсодержащий компонент в количестве до 1% (в пересчете на ортофосфорную кислоту)), используя маточник в качестве реакционной среды.4. Способ по п.3, отличающийся тем, что потери маточника восполняют добавками воды.5. Способ по п.3, отличающийся тем, что при многократном использовании маточник очищают от при1. A composition based on urea nitrate, characterized in that in addition to urea nitrate, the composition contains moisture not more than 4% and a phosphorus-containing component in an amount of up to 1% (in terms of phosphoric acid) .2. The composition according to claim 1, characterized in that phosphorus compounds such as phosphoric acid and its substituted derivatives, for example hydroxyethylidene diphosphonic acid (HEDPA), nitrilotrimethylphosphonic acid (NTFC), including stoichiometrically balanced in the composition in the form of a salt, in particular in the form of urea salts (especially if it is necessary for the phosphorus-containing component to be solidified) .3. A method for producing a composition based on urea nitrate and a phosphorus-containing component, characterized in that the process for producing the composition is carried out in two stages: in the first stage, a mother liquor is produced from a urea, nitric acid, phosphorus-containing component and water, which is an aqueous solution of urea, nitric acid and a phosphorus-containing component containing not more than 34% urea, not more than 16% nitric acid and not more than 6.3% of a phosphorus-containing component; in the second stage, the aforementioned composition (containing, in addition to urea nitrate, moisture of not more than 4% and a phosphorus-containing component in an amount of up to 1% (in terms of orthophosphoric acid)) is obtained from the urea, nitric acid, and phosphorus-containing component) using the mother liquor as the reaction medium. four. The method according to claim 3, characterized in that the loss of the mother liquor is supplemented with water additives. The method according to claim 3, characterized in that with repeated use, the mother liquor is cleaned from
