At the present time, the deepening strict regulations of national
environmental requirements and the increasing demand for clean
fuel bring new challenges to the development of deep desulfurization
technologies [1,2]. Thus, the ultra-deep desulfurization methods
of oil have become hot point in research. Dibenzothiophene
and its derivatives are regarded as the sulfides that are the most
difficult to remove sulfur. Meanwhile, realizing desulfurization in
industrial production generates the necessity to have date about
the physicochemical properties of these materials.
