2,4,5-三氯苯酚是一种杀菌剂,也是制备多种农药的中间体之一。多氯代苯酚类的化合物在农药和染料工业中是一种重要的原料。文献中,有关三氯苯酚的极谱特性很少报导,对2,4,5-三氯酚极谱法的研究更未见记载。本文仅就2,4,5-三氯酚经硝化作用后的极谱特性加以介绍。实验部分主要仪器和试剂 P04型自动记录极谱仪,以饱和甘汞电极为参比电极,用饱和氯化钾的琼脂盐桥同电解池相连接。硝酸:G.R.;硫酸:A.R.;乙醇:95％
2,4,5-trichlorophenol is a fungicide, but also one of the intermediates in the preparation of a variety of pesticides. Polychlorinated phenolic compounds are an important source of raw materials in the pesticide and dye industries. In the literature, the polarographic characteristics of trichlorophenol are rarely reported and no studies on polarography of 2,4,5-trichlorophenol have been described. This article only 2,4,5-trichlorophenol after the polarographic characteristics of the nitrification to be introduced. Experimental part of the main instruments and reagents P04 automatic recording polarography with saturated calomel electrode as the reference electrode, with saturated potassium chloride agar salt bridge connected with the electrolytic cell.
