Special Features in Pyrolysis Behaviour of IsoalkylaromaticsThe pyrolysis of cumene, sec. butyl- and tert. butylbenzene proceeds in a laboratory scale quartz vessel in the temperature range 600-750°C. Conversion occurs mainly via a radical-chain mechanism in the side chain in proportions, determined by the dissociation energies of the C—C- and C—H-bonds. Dealkylation was observed in greater amounts than for n-alkylbenzenes. It is interpreted by H-atom addition to the aromatic nucleus, followed by β-scission to benzene and isoalkenes. It was be shown, that H-atoms are formed by unusual reactions such as neophyl rearrangement and homolytic rupture of C—C-bonds in the side chain.
