MIXTURE FOR PROCESSING UREA CONTAINING FERTILIZERS Russian patent published in 2020 - IPC C05G3/90 C05G5/35 C05C9/00 

FIELD: agriculture; agrochemistry.

SUBSTANCE: mixture for processing fertilizer-containing fertilizers contains component A, at least one triamide (thio)phosphoric acid of general formula (I) R¹R²N-P(X)(NH₂)₂ and/or (thio)phosphoric acid diamide of general formula (II) R¹O-P(X)(NH₂)₂, in which X denotes oxygen or sulfur, R¹ and R² independently denote hydrogen, suitably substituted or unsubstituted 2-nitrophenyl, alkyl with 1–10 carbon atoms, cycloalkyl with 3–10 carbon atoms, heterocycloalkyl with 3–10 carbon atoms, aryl with 6–10 carbon atoms, heteroaryl with 6–10 carbon atoms or diaminocarbonyl, wherein R¹ and R² together with the nitrogen atom bonded thereto can also form a five-member or six-membered, saturated or unsaturated heterocyclic residue, which optionally can also contain one or two additional heteroatoms selected from a group consisting of nitrogen, oxygen and sulfur, and as component B 2-(N-3,4-dimethylpyrazole)succinic acid, which can also be in form of a salt, wherein the weight ratio of components A and B is in range of 1:1.5 to 1:5.

EFFECT: disclosed synergistic mixture of a urease inhibitor and a nitrification inhibitor for treating urea-containing fertilizers is characterized by high urease inhibition efficiency, provides for reduction of nitrogen losses with organic fertilizers and during storage of liquid-free manure, use of the mixture also reduces a load caused by ammonia to livestock premises.
