在恒容间歇反应器中，在400℃、425℃和450℃恒温下进行了1-甲基和1-乙基芘的热解反应，反应时间最长为300min。甲基芘的主要热解产物为芘和二甲基芘，乙基芘的主要热解产物为芘和甲基芘。这些结果表明，甲基和乙基芘中的芳基−烷基C−C键容易发生氢解。通过建立机理模型，检验了不同氢解机理的相对重要性。
The pyrolyses of 1-methylpyrene and 1-ethylpyrene were conducted at 400, 425, and 450°C in constant-volume batch reactors for holding times up to 300 min. The major products from methylpyrene pyrolysis were pyrene and dimethylpyrene whereas the major products from ethylpyrene pyrolysis were pyrene and methylpyrene. These results show that the aryl−alkyl C−C bond in methyl- and ethylpyrene is susceptible to facile hydrogenolysis. The relative importance of different hydrogenolysis mechanisms was examined through the development of mechanistic models
