| titleOfInvention | The synthetic method of 5- Amino 3 cyano -1- (2,6- dichlor-4-trifluoromethyl phenyl) pyrazoles |
| abstract | The invention discloses 5- Amino 3 cyano -1- (2,6- dichlor-4-trifluoromethyl phenyl) pyrazoles synthetic method, it include: at 0-5 DEG C, to 2, the sodium nitrite solution that the ethanol solution and mass concentration that 2,6- dichlor-4-trifluoromethyl aniline salt is added dropwise in the ethanol solution hydrochloride of 3- dicyano ethyl propanoate simultaneously are 40-45%；Reaction solution keeps the temperature 2-12h at 0-5 DEG C, until reproducibility reagent is added dropwise into reaction solution to remove excessive nitrous acid in reaction solution, until nitrous acid is removed completely in reaction solution after 2,6- dichlor-4-trifluoromethyl aniline≤0.5% in reaction solution；At 10-15 DEG C, ammonium hydroxide and ethyl alcohol are added in reaction solution, so that pH >=11 of reaction solution, keep the temperature 8-24h.The synthetic method has broken the technology prejudice of those skilled in the art, has saved cost, and substantially reduced the generation of " three wastes ". |
