Desulfurization of Petroleum Using Synthesized Novel Ionic Liquids and Betaine Moieties

Additional Funding Sources

The project described was funded by Idaho State University

Abstract

The purpose of this research is to synthesize ionic liquids that interact favorably with dibenzopyrroles and dibenzothiophenes that are common pollutants in crude oils as well as optimize a procedure for the extraction of these pollutants from crude oils. The synthesis of the ionic liquid betaine moieties was successfully performed using various dimethyl amines and ethyl bromoacetate. NMR analysis indicated that the major product of the reaction was the desired ionic liquids and betaine moieties.

The synthesized ionic liquids are able to extract carbazole pollutants from a model crude oil solution. However, the extraction efficiency is still lower than desired. Thus, the procedure for using the synthesized novel ionic liquids is still being optimized.
