EXPERIMENTAL AND THEORETICAL KINETICS OF HIGH TEMPERATURE FLUOROCARBON CHEMISTRY

Abstract

Ultraviolet absorption was used to measure the rate of formation of difluoromethylene (CF2) from decomposed CF3I, C2F6, and CF4 in excess argon behind shock waves. In some experiments pure CF4 was shocked. Data were taken over a temperature range from 1700 to 3000 K at total concentrations between 2(10 to the minus 5th power) and 5(10 to the minus 6th power) mole/cu.cm. A chemical, nonequilibrium shock-tube computer program was developed to analyze the CF2 kinetic profiles. By curve fitting the data, rate constants for a number of fluorocarbon reactions are obtained.
