A Shock Tube Study of H Atom Addition to Cyclopentene

A Shock Tube Study of H Atom Addition to Cyclopentene We report shock tube studies of the kinetics of H atom addition to cyclopentene and modeling of the subsequent decomposition of cyclopentyl. Hydrogen atoms were generated with thermal precursors in dilute mixtures of cyclopentene and a reference compound in argon. Addition of H to the double bond leads to a cyclopentyl radical that rapidly ring opens and decomposes to ethene and allyl radical. The process was monitored by postshock gas chromatographic analysis of ethene and rate constants determined relative to H atom displacement of methyl from 1,3,5‐trimethylbenzene (135TMB).

Abstract

We report shock tube studies of the kinetics of H atom addition to cyclopentene and modeling of the subsequent decomposition of cyclopentyl. Hydrogen atoms were generated with thermal precursors in dilute mixtures of cyclopentene and a reference compound in argon. Addition of H to the double bond leads to a cyclopentyl radical that rapidly ring opens and decomposes to ethene and allyl radical. The process was monitored by postshock gas chromatographic analysis of ethene and rate constants determined relative to H atom displacement of methyl from 1,3,5‐trimethylbenzene (135TMB). At 863–1167 K and 160–370 kPa, we find kH+ cyclopentene → ethene + allyl /kH+135 TMB →m‐xylene+ CH 3=10−0.196exp1995K/T and, with kH+135 TMB →m‐xylene+ methyl =6.70×1013exp−3255K/T cm 3 mol −1s−1, we obtain kH+ cyclopentene → ethene + allyl =4.27×1013exp−1260K/T cm 3 mol −1s−1
