| titleOfInvention | A kind of synthetic method of 1H-tetrazolium compound |
| abstract | The invention discloses a method for synthesizing a 1H-tetrazole compound. The synthesis method uses sodium azide, ammonium chloride and orthoformate to react in an organic solvent to prepare 1H-tetrazole. It is crystallized in a mixed solvent of ethyl ester to remove inorganic salts in the product, and a product of 1H-tetrazolium is obtained with high yield and high quality. In the synthesis method, no waste water is generated, and the organic solvent is rectified and recycled for use, which greatly reduces the production cost of 1H-tetrazolium, and simultaneously reduces environmental pollution. |
