The invention discloses a method for continuously synthesizing meta-di-alkane aminophenol. The technical scheme includes that continuous diazotization or continuous diazonium salt hydrolysis or continuous diazotization and diazonium salt hydrolysis is carried on raw materials such as di-alkane aminophenol, sodium nitrite and sulfuric acid, and after-treatment such as extraction is carried out to obtain the meta-di-alkane aminophenol which is a product. The method has the advantages that the raw materials can come from sufficient sources and are low in cost, processes for synthesizing the meta-di-alkane aminophenol are high in safety, products are high in yield, the method is little in waste gas, wastewater and industrial residue pollution, is green and environmental friendly and has a highindustrialization value, and the like. 本发明公开了种间二烷胺基苯酚的连续化合成方法，该方法以间二烷胺基苯胺、亚硝酸钠、硫酸等为原料，经连续化重氮化或连续化重氮盐水解或连续化重氮化和重氮盐水解的技术方案，及萃取等后处理得到产物。本发明方法具有原料来源充足、价格低廉，合成工艺安全性高，产品收率高，三废污染少、绿色环保等特点，具有较高的工业化价值。
