It is shown that the formation of non-chromatographable products of Α-methylstyrene condensation with polycyclic aromatic compounds of pitches occurs simultaneously. The dependences of Α-methylstyrene conversion, the selectivity for cumene and condensation products on the temperature and reaction time, the ratio of pitch/Α-methylstyrene are determined. The amount of hydrogen transferred from pitches to Α-methylstyrene was determined, and the results obtained were compared with the literature data on the transfer of hydrogen from pitches obtained using anthracene as a hydrogen acceptor.
