摘　　要：对渤海PL19-3原油环烷酸分离提纯后,采用红外光谱、元素分析、气相色谱质谱等手段对环烷酸组成结构及分布进行分析。结果表明:渤海PL19-3原油中石油酸不仅存在于柴油馏分中,在减压蜡油中仍然有较高含量;环烷酸主要是以一环、二环、三环为主,芳环含量较低,并随馏分变重结构趋于复杂。The naphthenic acid in Bohai PL 19-3 crude was separated and purified firstly. Then,the composition,structure, as well as the distribution of naphthenic acids were analyzed and characterized by elemental analysis,IR and GC-MS. The results indicate that naphthenic acid not only consists in the diesel oil fraction,but also in vacuum gas oil at high percentage. The main components of naphthenic acids are mono-,diand tri-cyclic ones,with few aromatic ring ones. And in heavier distillations,the structures get more complicated.
