| titleOfInvention | How to prepare aminophenol |
| abstract | The present invention includes reacting a compound of Formula 3 or 4 with an organic halide of Formula 5 under aqueous acidic conditions, with periodic addition of an acid trapping agent so that there is no need to continuously monitor the pH of the reactants. It relates to a process for the preparation of N, N-unsubstituted aminophenols of the general formula (1) or (2).n n n Formula 1n n n n n n n n Formula 2n n n n n n n n Formula 3n n n n n n n n Formula 4n n n n n n n n Formula 5n n n R 2 Xn n n In the above formula,n n n R 1 and R 2 are the same or different and are each saturated or unsaturated aliphatic hydrocarbyl, cycloalkyl, aralkyl (the phenyl ring of aralkyl may be further substituted), alkoxyalkyl, or cycloalkylalkyl, provided that R 1 And R 2 is not methyl at the same time;n n n R 3 represents hydrogen or R 1 ;n n n R 'represents hydrogen, halogen, nitro, cyano, alkyl or alkoxy;n n n X represents a halogen. |
