【Abstract】 A new process of synthesize oaminophenol methyl ether from onitrophenol methyl ether by catalytic hydrogenation, using ammonia synthesis gas instead of pure hydrogen were developed. The effect of reaction conditions on the yield of o-aminophenol methyl ether was also discussed. The yield of oaminophenol methyl ether was above 93% under the optimum reaction condition, the consumption of catalyst 1%, the reaction temperature 120 ℃, the reaction pressure 5 MPa, and the reaction time 3 h.更多还原
