| Abstract: |
| 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 , di and tri cyclic ones, with few aromatic ring ones. And in heavier distillations, the structures get more complicated. |
