Process for preparing N-alkylaminophenols |
| abstract |
A process for preparing an N-alyklaminophenol represented by the formula (III): <CHEM> wherein R1 represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms; and R2 represents an alkyl group having from 1 to 6 carbon atoms, which comprises reacting an aminophenol represented by the formula (I): <CHEM> wherein R1 is as defined above, with an alkyl halide represented by the formula (II): R2X (II) wherein R2 is as defined above; and X represents a halogen atom, at 80 DEG -120 DEG C at 3-30 kg/cm<2>G pressure in an autoclave in the presence of water under heat and pressure, using ammonia as an acid scavenger, 1-2 mols of alkyl halide are used per mol of alkyl group and 1-3 mols ammonia per mol compound (I). The ammonia is preferably introduced continuously while the pH is 4-10, and with 0.05-4 parts by wt. water per wt. of aminophenol. |
