探讨了乙醇和水的混合介质中，通过铁粉还原２，５－二甲氧基－４－氯硝基苯制备２，５－二甲氧基－４－氯苯胺的反应条件，即硝基物与铁粉的摩尔比、硝基物与冰醋酸的摩尔比、溶剂用量、溶剂中乙醇和水的体积比、电解质的种类及硝基物与电解质的摩尔比等条件对还原产物的影响，最后确定了２，５－二甲氧基－４－氯苯胺的最佳制备条件。
The reaction conditions of 2,5-dimethoxy-4-chloronitrobenzene with 2,5-dimethoxy-4-chloroaniline by iron powder reduction in a mixed medium of ethanol and water were discussed. That is, The molar ratio of substance to iron powder, the molar ratio of nitrate to glacial acetic acid, the amount of solvent, the volume ratio of ethanol to water in the solvent, the type of electrolyte and the molar ratio of nitro compound to electrolyte, Finally, the best preparation conditions of 2,5-dimethoxy-4-chloroaniline were determined.
