Elementary processes in combustion and sooting of coal derived fuels. Progress report: 1st year, 1st quarter, August 10-November 9, 1982. [Butadiene radicals]
This period reflects the initial quarter-year of a three-year program to investigate the kinetics and mechanisms of radical-radical and radical-molecule reactions important in combustion and sooting of high aromatic content fuels. The basic approach involves the initiation of a reaction with laser techniques with subsequent probing of intermediates and products with real-time probes of chemical analysis. During the first few months some time was necessary for the incorporation of new equipment and project development. In this report brief outline of work and progress are described for the following projects: chemistry of butadiene radicals; decomposition of phenyl radicals; and jet cooling of reaction intermediates. A CO/sub 2/ laser is used to dissociate 2-chloro-1,3-butadiene to butadiene radical through elimination of a chlorine atom. Phenyl radical is also obtained by dissociating chloro- and bromobenzene with a CO/sub 2/ laser. Fourier Transform Infrared Spectroscopy is used to follow the concentrations of final products.
