The thermal decomposition of ethylbenzene has been investigated behind reflected shock waves over the temperature and pressure ranges of 1350–2080 K and 0.25–0.5 atm using a 1.6% C 8 H 10 Ne mixture. Major products of the pyrolysis are C 7 H 8 , C 7 H 7 , C 6 H 6 , C 4 H 2 , C 2 H 4 , C 2 H 2 , and CH 4 ; C 8 H 8 appears throughout the temperature range as a minor product. Comparison of the product profiles obtained by time‐of‐flight mass spectrometry and the results of model calculations strongly supports the initiation step of β CC bond homolysis for C 8 H 10 dissociation. A 51 kinetic step reaction mechanism with 24 species was formulated to model the temperature and time dependence of the major products observed in our experiments.
