## Abstract The homogeneous thermal isomerization of cyclopropane to propene was studied in the presence of large excesses (99.6%β99.8%) of argon or helium diluent. Reaction temperatures ranged from 1038Β°β1208Β°K, and total gas pressures were varied from 533 to 5097 torr. The comparativeβrate single

β¦ Synopsis
Cyclopropane mixtures diluted with argon were heated to temperatures in the range 1 loo-1450 K behind incident and reflected shock waves. The rate of isomerization of cyclopropane to propylene was measured by tracing the time variation of absorption at 3.39 pm. The rate constant expression k=4.60~ 10 14exp( -62.5 kcal/RT) s-' was determined, in accord with extrapolation from lower-temperature experiments.

1,a-Butadiene diluted with Ar was heated behind reflected shock waves over the temperature and the total density ranges of 1100-1600 K and 1.36 X mol/cm3. The major products were 1,3butadiene, 1-butyne, 2-butyne, vinylacetylene, diacetylene, allene, propyne, CzHs, CzH4, CzH2, CH4, and benzene, which
## Abstract Cyclopropane in argon mixtures was heated in a singleβpulse shock tube, and syringes were used to withdraw samples from both the central gas slug and the gas adjacent to the tube walls. Differences were observed in the measured conversion, with larger conversion found in the center loca
The high-temperature decomposition of propylene has been investigated in a single-pulse shock tube in the temperature range 1160-1700 K. The stable products observed were hydrogen, methane, ethylene, acetylene, ethane, allene and propyne. The rate of evolution of the different products was found to
