| titleOfInvention | The method of purification phenylhydrazine-β-carboxylate compound |
| abstract | Provide a kind of purification process, it is by efficiently separating and remove the chloroaniline compound (II) included in the crude product of phenylhydrazine β carboxylate compound (I), prevent phenylhydrazine β carboxylate compound (I) from losing simultaneously, obtain phenylhydrazine β carboxylate compound (I) product of the purification with the chloroaniline compound (II) reducing concentration.The method of this purification phenylhydrazine β carboxylate compound (I) includes mixing phenylhydrazine β carboxylate compound (I) crude product containing chloroaniline compound (II) and water and the organic solvent that can be separated from water in the presence of a mineral acid, and then this mixture is separated into the oil reservoir containing phenylhydrazine β carboxylate compound (I) and water-bearing layer. |
