Abstract
This thesis is mainly about the production of 2, 5 - dimethoxy -4 - chloro-aniline, which is produced from 2, 5 - dimethoxy - 4 - chloro-nitrobenzene and iron powder with mixture of EhOH - H_2O as medium. The author studied many reduction conditions in the process of this production, and their effects on the product. These conditions include molar ratios of nitrobenzene to iron powder and to aceticacid, volume ratio of EhOH to H_2O, kind of electrolyte and molar ratio of nitrobenzene to electrolyte, etc. In the end, the author proposed the optimum condition to produce 2, 5 - dimethoxy - 4 chloro-aniline.
