Popis:	1. 1. A study was made of the precipitation of asphaltenes from benzene solutions in the form of complexes with Lewis acids. It was shown that in efficiency of precipitation of asphaltenes the acceptors examined may be arranged in the order: TiBr4TiCl4>SnBr4SbCl5SnCl4FeCl3SbCl3. 2. 2. With all the Lewis acids, mentioned asphaltenes with a higher nitrogen content (basic) and higher aromaticity are separated.
