Aminophenol method for pressurized CO2 / H2O system prepared from N- phenyl hydroxylamine

Description: A pressurized CO2 / H2O system prepared from N- phenyl hydroxylamine method aminophenol, belonging to the technical field of fine chemicals. Characterized in that: a concentration of an aqueous solution of N- phenyl hydroxylamine 1 × 10-3-4 × 10-1mol·L-1, and the CO2 pressure 0.5-14MPa, the reaction temperature is 40-140 ℃ under the reaction was stirred 0.25-12h, namely the generation of amino phenol. Effects and benefits of the present invention are: a reaction system of water and pressurized CO2 to carbonic acid is formed as the promoter, avoiding the use of permanent acid after the reaction releasing CO2, and the reaction system can be realized.
