    Composition and Distribution of Naphthenic Acids in Penglai Crude Oil with High Acid Number

      摘要
    • 摘要: 采用以乙醇胺为碱性组分的复配溶剂将蓬莱高酸原油中的环烷酸分离出来,并借助红外光谱、元素分析、质谱、核磁共振波谱等手段对其组成和结构进行了探讨,认为蓬莱高酸原油所含环烷酸的平均相对分子质量为278,平均分子式为C18H30O2,其中主要为一环和二环的一元羧酸,两者总量达66%。碳数分布为C9~C28。环烷酸的主要成分为饱和酸,芳香酸含量很少。

       

      Abstract: Naphthenic Acids(NAs) were separated from the Penglai acidic crude oil by ethanolamine,and their compositions and structures were analyzed by element analysis and characterized by different spectroscopic methods such as IR,MS,and NMR.The NAs in Penglai crude oil were mainly unitary acids containing one or two rings.The carbon number ranges from 9 to 28,the average molecular weight was 278 and the empirical formula averaged to C_(18)H_(30)O_2.
