Abstract

The rate of thermal dehydrogenation of cyclopentene was studied in a single-pulse shock tube. Reactant mixtures consisted of 0.25 and 1.00% cyclopentene in argon, and total gas pressures were about 1 atm. Reaction temperatures were determined via the comparative rate technique, using the decomposition of tert-butyl alcohol as the internal standard reaction. Over the temperature range 1020-1189°K the data support a first-order rate equation, with rate constants in units of sec -1 given by log k(C 5H 8 → C 5H 6 + H 2) = 13.35 - [60.0 × 10 3/4.58T°K]. The reaction was essentially free of complications over this temperature range, but significant concentrations of side products were formed at higher temperatures. A separate study of the products formed from cyclopentadiene decomposition suggests that these side products were produced primarily from cyclopentene. Possible mechanisms are discussed.
