Abstract

The homogeneous unimolecular isomerization of cyclopropane has been studied in two independent sets of single-pulse shock tube relative rate experiments. Concentration of cyclopropane in argon ranged from 0.25 to 10%, total final pressures were 0.5-7 atm, and temperatures were 970-1265°K, with residence times of 180-900 μsec. The results, corrected by RRK theory for falloff, are in excellent agreement with conventional, lower temperature investigations and are consistent with a rate constant k_∞ = 10^15.2 × exp(-65,000/RT) sec^-1.
