在有机化学中,含有羟基的酚类化合物与氯化高铁常常产生颜色反应,所以在有机分析化学中作为一种定性分析方法,常利用氯化高铁来检验它们。 氯化高铁与酚类化合物产生颜色,这种颜色的来源是由於高铁离子与酚某(OR)~-形成络离子,所以可以应用Job在1928年所提出的连续变化法(The Method of Continuous Variation)研究这些离子的组成。因为该法作为一种光吸收法(物理化学分析法之一)对於在溶液中生成的络离子,特别是这些络离子只存在於溶液中很难
In organic chemistry, phenolic compounds containing hydroxyl groups frequently react with ferric chloride to produce a color reaction. Therefore, they are often used as a qualitative analytical method in organic analytical chemistry by using high-speed ferric chloride. Chlorinated high-speed rail and the phenolic compounds produce color, the source of this color is due to high iron ions and phenolic (OR) ~ - complex ions, so you can apply Job in 1928 proposed by the continuous change method (The Method of Continuous Variation ) Study the composition of these ions. Because this method as a light absorption method (one of the physicochemical methods) for the complex ions generated in solution, especially the complex ions only exist in solution is difficult
