| titleOfInvention | Process for the preparation of phenylhydrazines |
| abstract | A process for the preparation of a phenylhydrazine or an inorganic acid salt thereof of the formula (1): n n nwherein X is a hydrogen or halogen atom; Y is a halogen atom; and W is a hydrogen atom or —ZR in which Z is an oxygen or sulfur atom, and R is a hydrogen atom, an alkyl group, a haloalkyl group, and so on, by the hydrolysis of a phenylhydrazine derivative of the formula (2): n n nwhere X, Y and W are the same as defined above, and the Q groups are a hydrogen atom, an ammonium group or an alkali metal atom in the presence of water and an inorganic acid, in which the concentration of the inorganic acid is at least 6 moles per 1 kg of water in a reaction system. |
