| titleOfInvention | Preparation method of 1-phenyl-5-mercapto tetrazole |
| abstract | The invention provides a preparation method of 1-phenyl-5-mercapto tetrazole. According to the invention, sodium azide and phenyl isothiocyanate are used as reaction raw materials for preparing 1-phenyl-5-mercapto tetrazole, and the reaction temperature is controlled to be 90-95 ℃, the reaction time is 110-130 min, so that the sodium azide and the phenyl isothiocyanate can be fully subjected to an azide reaction under mild reaction conditions without using a catalyst; meanwhile, the preparation method provided by the invention is simple to operate, does not need complex production equipment, and has small environmental pollution in the production process; in addition, the preparation method provided by the invention is simple in post-treatment operation, low in production cost and easy to realize large-scale industrial production. The results of the embodiment show that when the method provided by the invention is used for large-scale industrial production, the yield of the target product 1-phenyl-5-mercapto tetrazole can reach 94.8%, and the actual production needs can be met. |
