加氢法合成对乙酰氨基苯酚（扑热息痛）

SYNTHESISOFN-ACETYL-P-AMINOPHENOL BY HYDROGENATION

以对硝基苯酚为原料，经催化加氢和酰化合成了对乙酰氨基苯酚。讨论了温度、催化剂用量、硝基物浓度等因素对反应的影响，产品收率可达８４％。

Abstract A study for synthesizing N-acety1-p-aminophenol by catalytic hydrogenation and acetylation from p-nitrophenol is presented.The factors such as temperature,the dosage of the catalyst and the concentration of nitro compound which influence the reaction are discussed.On the optimum conditions,the yield is about 84 %。
