邻苯基苯酚是一种优良消毒剂和杀菌剂。根据文献报道,专门用于测定邻苯基苯酚的方法不多。在碱和碘的存在下,邻苯基苯酚能生成有色物质,用甲苯萃取后,可进行比色分析,此法用作定量分析,较难掌握。将苯基苯酚的丙酮溶液在层析滤纸上点样,吹干后,用经过水饱和的矿油精作展开剂,用硝酸铈铵作显色剂,邻-、间-、对-三种苯基苯酚的Rf值各为0.96,0.77和0,根据显色斑点的大小,可计算出各
O-phenylphenol is a good disinfectant and bactericide. According to the literature, there are not many methods for the determination of o-phenylphenol. In the presence of alkali and iodine, o-phenylphenol can generate colored material, extracted with toluene, the colorimetric analysis can be used, this method for quantitative analysis, more difficult to grasp. The phenol solution of acetone phenol chromatography on the filter paper, after drying, with water-saturated mineral oil as solvent, with ceric ammonium nitrate as a developer, o-, m -, p - three benzene Rf values for phenol are 0.96, 0.77 and 0, respectively. Based on the size of the color spots,
