摘　　要：在乙醇和水的混合介质中，利用锌粉还原2，4-二硝基氟苯制备2-氟-5硝基苯胺。其制备2-氟-5硝基苯胺的适宜条件：在50～60℃下回流，2，4-二硝基氟苯与锌粉的摩尔比为1：4，混合试剂中乙醇和水的体积比为3：2，收率达70．1％。In this paper, 2-fluorin-5-nitroaniline was prepared by reduction of 2,4-dinitrofluorin benzene catalyzed by zinc powder in the mixed solvent of ethanol/water. The optimum conditions were as follows ： when mol ratio of 2,4-dinitrofluorin benzene to zinc power was 1：4, mol ratio of ethanol to water in the mixed solvent was 3：2 under refluxing at 50--60 ℃, the yield reached 70.1% .
