| Abstract: | A new process has been developed to synthesize p-aminophenol methyl ether from p-nitrophenol methyl ether by catalytic hydrogenation,using ammonia synthesis gas instead of pure hydrogen.Study of the effect of reaction conditions on the yield of p-aminophenol methyl ether was also conducted.The yield of p-aminophenol methyl ether was above 96% under the optimum reaction condition,i.e.the consumption of catalytic agent was 1%,the reaction temperature was 140℃,the reaction pressure was 4MPa,and the reaction time was 3h. |
