“…Extraction of asphaltenes and their components by supercritical fluids of solvents is represented by a wide range of these solvents. There are works describing processes with supercritical fluid extraction, where asphaltene molecules were treated with supercritical solvents such as carbon dioxide, water, toluene, pentane, benzene, propane, various alcohols, , and mixed compositions . But those are just a small part of the articles in this research area.…”

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.

Capillary supercritical fluid chromatography with flame ionisation detection was used for the separation of some underivatised triterpene acids such as betulinic, oleanolic, polpunonic and ursolic acids. Supercritical fluid chromatography showed advantages over capillary gas chromatography since derivatisation was not required and separation was obtained in less than 15 min with high efficiency and good resolving power.
