摘　　要：根据反应原料的不同,介绍了3,5-二甲基苯胺的六种主要合成方法,阐述了不同的合成方法得到的不同结果,比较了各种方法的可行性。其中3,5-二甲基苯酚法和2,4-二甲基苯酚法在工业生产中应用最广。前者因为原料价廉易得,且反应一步完成,副反应较少,最受研究者关注;后者芳伯胺法是最新研究的合成方法。The synthetic methods of 3,5-dimethylaniline were introduced in this paper. The different results were obtained by the different synthetic methods, and the feasibilities of the different synthetic routes were discussed. The six synthetic methods of 3,5-dimethylaniline were described based upon different raw materials. Among those methods, some methods could not be applied in the industry because of the raw material and its price. The methods with 3,5-xylenol and 2,4-xylenol were often used in the industrial production. 3,5-xylenol method had become very common because of available raw material, low price and few side-reactions. In addition, the aniline method was currently developed.
