| titleOfInvention | A kind of preparation method of high purity 1 H -1,2,3- triazole |
| abstract | The present invention relates to a kind of high purity 1 Hs -1,2, the preparation method of 3- triazole, comprising the following steps: step 1, using benzotriazole as raw material, potassium permanganate is oxidant, water is solvent, under alkaline condition, high purity 1 H -1,2 is obtained by oxidative cleavage, purification drying, 3- triazole -4,5- dicarboxylic acids；1H-1 obtained in step 2, step 1,2,3- triazole -4,5- dicarboxylic acids are in N, the effect of dinethylformamide solvent catalyst neutralisation is lower to carry out decarboxylic reaction, obtains target product high purity 1 H -1,2 by purification, 3- triazole, wherein catalyst is the mixture of quinoline, pyridine or both.The present invention makees catalyst with pyridine or quinoline in step 2 and traditional oxide with copper powder or copper is replaced to make catalyst, and good reaction selectivity, high income, product purity are high and stability is more preferable. |
