| | N-(n-butyl)thiophosphoric triamide Usage And Synthesis |
| Chemical Properties | White Crystalline Solid | | Uses | A urease inhibitor | | Flammability and Explosibility | Non flammable | | Synthesis | General procedure for the synthesis of n-butylthiophosphoric triamine from the compound (CAS: 6141-81-7): first, ammonia was passed through cold hydrazine and externally observed until liquid ammonia was formed. A cooling device was started in a four-necked flask equipped with a stirrer to maintain the reaction temperature at -45°C. Subsequently, 12.75 g of liquid ammonia was added to the flask and the pre-cooled reaction solution was added dropwise stepwise. The dropwise addition process was controlled to be completed within 1.5 hours. Samples were taken during the reaction and when the content of N-butylamino thiophosphoryl dichloride decreased to 2% of the total mass, the reaction temperature was raised to 25°C. The reaction was continued until the substitution reaction was completed, with a total reaction time of 2 h 5 min. At the end of the reaction, the product was filtered, washed and vaporized, and finally recrystallized from n-hexane to obtain N-n-butylaminophosphorothioic acid triamine with a purity of 98.7% and a yield of 95.1%. | | References | [1] Patent: CN105399767, 2016, A.
