“…This work presents a method for the quantitative separation of asphaltenes and nitrogen bases by passing an inert gas containing TiCl 4 through a hexane solvent in which the asphaltene fractions are dissolved. As the authors of the work write, the method is suitable for fractionation of resins from asphaltene fraction …”

“…As the authors of the work write, the method is suitable for fractionation of resins from asphaltene fraction. 116 Researchers from the Central University of Venezuela treated solutions of asphaltenes in cumene with p-nitrophenol, resulting in a solid that precipitated after 3 days. 117 For the studied samples of asphaltenes, 48−70% of the sample can be precipitated as a result of this treatment.…”

This review contains some actual information about more interesting and perspective methods of coal and petroleum asphaltenes separation, fractionation, extraction, adsorption, and complexation. These are the most convenient and simple methods for isolating various components of asphaltenes. These methods are based on the electrostatic and donor–acceptor properties of the used reagents and on unique and incompletely understood phenomena. A promising area is the use of ionic liquids as a convenient and mild isolation of asphaltene components. Understanding and identifying the diverse molecular composition of asphaltene components will help one to understand their nature more fully in the future and, more precisely, physicochemical interactions and phenomena.
