- Abstract
- The electron attachment coefficients of a number of halogenated hydrocarbons, particularly flame inhibitors, were determined as a function of the average agitation energy of electrons between 0.1 and 1.2 e.v. at atmospheric pressure and room temperature. A sensitive electron swarm technique was used for the measurement. The gas under study was introduced, at low concentrations, by means of a nitrogen carrier into an ionization chamber. The electron attachment coefficients for the compounds examined differed by a factor of 10(6) between a low value for CF4 and a high for CF2Br2. All inhibitors studied were found to have a higher electron attachment coefficient than does O2. It was found, with some exceptions, that gases reported as effective hydrocarbon flame inhibitors exhibited high electron attachment coefficients.
