The Shock Tube Isomerization of Cyclopropane with Infrared Analysis,
Abstract
In a continuing effort to develop kinetic analyses in shock tubes, the isomerization of cyclopropane to propylene was investigated. Three aspects of the problem were investigated: the theoretical analysis, the experimental infrared method of analysis, and the mathematical analysis. The test gas mixtures ranged from 0.1 to 5% cyclopropane in Argon. The temperature range was 1000 - 1350K. Kinetic measurements were made by means of infrared emission measurements at 4.79 microns. This band corresponds to the V5+V10 combination band in the IR absorption spectrum of cyclopropane. A plot of the logarithm of the intensity of emission versus time was prepared. It was discovered that the rate constants determined show a dependence on the cyclopropane concentration although they are independent of total or argon concentration. A discussion is given which indicates that the conventional steady-state assumption may not be valid for reactions in a shock tube. (Author)
