Abstract:Saponified chloro-naphthenic acid extraction system synthesis modified by naphthenic acid by four processes which are sequential naphthene oxychloride, chloro-naphthene oxychloride, chloro- naphthenic acid, the admixture and saponification of chloro- naphthenic acid, isooctyl alcohol, sulfonated kerosene has been researched in this article. The results of the testing and analysis of the intermediate and end products organic phase formed in the synthetic process by infrared spectroscopy shows that saponified chloro-naphthenic acid extraction system can be synthesized successfully by the synthetic method.
