Popis:	The paper reports the results of the fractional extraction of petroleum asphaltenes using a toluene/acetone mixture. This method was shown to be effective in extracting polyaromatic structures with various properties and in predicting a number of their composition parameters and structural properties, such as molecular weight, condensation level, aliphaticity, the number of paramagnetic centers, and metal content. It was found that the fractional extraction from petroleum asphaltenes with a toluene/acetone (60 : 40) mixture produces 47.4 wt % of polyaromatic structures with increased condensation level. Such asphaltene structures can be considered as graphene precursors and can be used for the preparation of various carbon materials.
