在水文地球化学油气普查勘探中,酚系物的地球化学分布特征是一种比较可靠的地球化学标志。本文采用薄层层析法对油田水、非油田水中的酚系物进行分离、鉴定和研究。 1.分析原理 在碱性条件下,酚系物与对硝基偶氮苯反应,形成不同的偶氮酚类化合物,在层析板上展开,并在二乙胺的碱性条件下显色分离。酚苯物存在不同颜色的着色点产生明显区别;苯酚Rf0.20—0.25砖红色、间—甲酚Rf0.26—0.33棕红色、邻—甲酚
In hydrogeochemical hydrocarbon exploration exploration, the geochemical distribution of phenolic compounds is a more reliable geochemical marker. In this paper, thin layer chromatography method was used to separate, identify and study phenolic compounds in water and non-oilfield water. 1. Analysis Principle Under alkaline conditions, phenolic compounds react with p-nitroazobenzene to form different azo phenolic compounds, which are developed on a chromatographic plate and developed in the basic condition of diethylamine Separated. There were obvious differences in the color points of phenols and phenols; Phenols Rf0.20-0.25 brick red, m-cresol Rf0.26-0.33 reddish brown, o-cresol
