一种2-氨基-4-硝基苯酚的制备方法
摘要：
本发明公开了一种2-氨基-4-硝基苯酚的制备方法。本发明提供了一种2-氨基-4-硝基苯酚的制备方法，其包括以下步骤：催化剂存在的条件下，将2,4-二硝基苯酚与水合肼进行还原反应，制得2-氨基-4-硝基苯酚，所述的催化剂为六水合三氯化铁(FeCl3·6H2O)和活性炭的组合。本发明的制备方法反应条件更温和、无副产物、经济环保、后处理简单，反应收率高，适合于工业化生产。
摘要（英）：

The invention discloses a preparation method for 2-amino-4-nitrophenol. The preparation method for the 2-amino-4-nitrophenol, provided by the invention, comprises the following step: subjecting 2,4-dinitrophenol and hydrazine hydrate to a reduction reaction in the presence of a catalyst, thereby preparing the 2-amino-4-nitrophenol, wherein the catalyst is a combination of ferric chloride hexahydrate (FeCl3.6H2O) and activated charcoal. The preparation method disclosed by the invention has the advantages of milder reaction conditions, no byproduct, economical efficiency, environment-friendliness, simple aftertreatment and high reaction yield, thereby being adaptable to industrial production.
