苯二酚

苯二酚即二羟基苯，苯分子中两个氢原子被两个羟基取代后的衍生物。

化学式为C₆H₄(OH)₂，有以下三个异构体：

邻苯二酚（Catechol），又称“儿茶酚”；
间苯二酚（Resorcinol），又称“雷琐酚”；
对苯二酚（Hydroquinone），又称“氢醌”。

邻苯二酚
间苯二酚
对苯二酚

这三种二元酚的性质很相类似，都有还原性及和三氯化铁发生颜色等反应。它们在染料、药物工业中有重要的用途。

These aromatic compounds are classed as phenols. There are three isomers of benzenediol: 1,2-benzenediol (the ortho isomer) is commonly known as catechol, 1,3-benzenediol (the meta isomer) is commonly known as resorcinol, and 1,4-benzenediol (the para isomer) is commonly known as hydroquinone.
