β¦ Synopsis
An experimental and analytical study of the oxidation of acetylene and ethylene behind incident shock waves was carried out over the temperature range 1815-2365 K at reaction pressures between 1.1 and 1.7 atm. The oxidation process was monitored by measuring radiation from carbon dioxide, carbon monoxide, and the reaction O + CO ~ CO 2 + hr. The recordcd emission profiles were analyzed to obtain concentrations for carbon dioxide, carbon monoxide, and the product of oxygen atom and the carbon monoxide concentrations. On the basis of this data and induction time data reported in the literature, kinetic models for acetylene and ethylene oxidation were assembled. The effect of adding other reactions to the proposed mechanisms is also discussed.
EXPERIMENTAL APPARATUS AND MEASUREMENTS
All the experiments were carried out behind incident shock waves in an 8.9-cm i.d. stainless-steel shock tube. Two different test sections were used during these studies. The experiments with ethyl-

The thermal decomposition of acetylene has been studied in the temperature and pressure regimes of 1900-2500 K and 0.3-0.55 atm using a shock tube coupled to a time-of-flight mass spectrometer. A series of mixtures varying from 1.0-6.2% CzHz diluted in a Ne-Ar mixture yielded a carbon atom density r
## Abstract Nine mixtures of acetylene and oxygen diluted in argon were studied behind reflected shock waves at temperatures of 1150β2132 K and pressures of 0.9β1.9 atm. Initial compositions were varied from very fuelβlean to moderately fuelβrich, covering equivalence ratios of 0.0625β1.66. Two mor
A study of the thermal decomposition of an acetylene-ethane-d6 mixture indicates that the rate constant for hydrogen abstraction from acetylene by methyl is more than 20 times less than for abstraction from ethane. Isotopic exchange is initiated by a rapid reaction between product D atoms and C2H2.
## 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
