| titleOfInvention | PROCESS FOR PURIFYING CRUDE P-AMINOPHENOL |
| abstract | The crude p-aminophenol prepared by transposition of nitrobenzene by reduction is purified by contacting, with a water-immiscible solvent, an aqueous solution of crude p-aminophenol in the form of a strong acid salt. said solvent extraction, the crude p-aminophenol is subjected to oxidizing conditions sufficient to oxidize the impurities, but not the p-aminophenol. Application of pure p-aminophenol: intermediate in the manufacture of dyes and analgesic and antipyretic drug known as paracetamol. |
