Urea-based blend composition and method for the manufacture thereof

The invention relates to a solid, particulate, urea-based blend composition comprising a urea-based compound in particulate form, one or more components in particulate form, selected from the group of nitrates, phosphates, sulphates and chlorides, and a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), wherein the urea-based blend composition is further characterized in that it comprises one or more reactive alkaline or alkaline-forming inorganic or organic compounds. The composition according to the invention has been stabilized against the degradation of a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT). The invention further relates to a method for the manufacture of the claimed solid, particulate, urea-based blend composition.

A continuous reaction synthesis N - alkyl thio phosphoric triamide

The invention discloses a method for synthesizing N-alkylthiophosphoryl triamide through a continuous reaction. The method comprises the following steps: 1, mixing thiophosphoryl chloride with an organic solvent, pre-cooling the obtained mixture in a heat exchanger to -5-0DEG C, mixing the material with an aminated compound pre-cooled to -5-0DEG C, and reacting the obtained mixture in a micro-reactor to obtain N-alkylthiophosphoryl dichloride at the outlet of the reactor; and 2, allowing N-alkylthiophosphoryl dichloride to directly enter an ammoniation reactor, carrying out an ammoniation reaction on N-alkylthiophosphoryl dichloride and ammonia gas, and post-processing after the ammoniation reaction is completed to obtain N-alkylthiophosphoryl triamide. N-alkylthiophosphoryl triamide is synthesized through a micro-reaction technology with high mass transfer and heat transfer efficiency, so conversion of intermittence to continuity is realized, the operating step is simplified, and the reaction yield is improved.

Synthesis method for urease inhibitor and application of urease inhibitor

The invention relates to a synthesis method for urease inhibitor and application of the urease inhibitor and belongs to the technical field of fertilizer synergists. The synthesis method includes the steps that n-propylamine/n-butylamine and phosphorus oxychloride serve as initial raw materials and are mixed with a solvent respectively to form two mixtures; an acid-binding agent is added to the two mixtures, the first temperature process temperature is adjusted to 10-50 DEG C, pressure is controlled to 0-0.5 MPa, after a first temperature process reaction, the temperature is reduced to 0-30 DEG C, and ammonia gas is introduced for a second temperature process reaction; a crude product is obtained after the second temperature process reaction is completed, and the finished product is obtained after the crude product is layered and then treated. The synthesis method is applied to preparation of the urease inhibitor and special urea and has the advantages of being short in processing flow, fewer in product impurities, high in utilization rate and good in heat stability, achieving continuous production and the like.
