Method for hydrogenating nitrobenzene to p-aminophenol in one step |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for producing p-aminophenol from nitrobenzene in one step with an inexpensive and efficient catalyst. SOLUTION: The present invention relates to a method for producing an aqueous acid, comprising the steps of: Hydrogenation of nitrobenzene over one or two Ni catalysts at a temperature of 0 ° C. for 1-4 hours in one step -To provide a method for producing aminophenol. The reaction mixture obtained was ethyl acetate, cyclohexane, Alternatively, the mixture is extracted with an organic solvent such as toluene, the aqueous layer containing PAP is separated, and the mixture is neutralized with an ammonia solution to recover solid p-aminophenol. |
