辽河原油直馏柴油馏分中羧酸含量和结构的探讨

Discussion on content and structure of petroleum carboxylic acids in the diesel oil fraction of liaohe oil

采用醇碱水溶液萃取方法分离出辽河油直馏柴油馏分中的石油羧酸(主要为环烷酸),采用重量法测出的分离效率不低于90％;用色谱、色谱质谱联用、红外光仪器分析手段对石油羧酸的化学结构进行了较详细的研究,发现了该馏分中石油羧酸在组成和结构方面的一些特征。

The petroleum carboxylic acids(mainly naphthene acids)in the diesel oil of Liaohe oil isolat- ed by the extraction with solution of a1coholic sodium hydroxide,and the efficiency is not lower than 90%; The chemical structure of these carboxylic acids are studied in detail by the use of GC,GC--MS,and IR techniques. Some characteristics of composition and structure of our company's petroleum acids are discov- ered.
