Abstract:

The relative rate constants for the reactions between ethyl and n-propyl free radicals are required for radiolysis calculations. The preliminary phases of an investigation to determine these constants have been completed. 1-Propaneazoethane C2H5NNC3H7 was selected as the source of free radicals. A synthesis was devised from hydrazine and accomplished. The compound was decomposed by exposure to high energy bursts of ultraviolet radiation from a flashtube. This decomposition resulted in the formation of nitrogen, ethyl free radicals, and propyl free radicals. A reaction scheme for the radicals was proposed and equations for the relative rate constants, in terms of product concentrations, derived. The product concentrations were then determined by gas chromatography, but the initial results are too sparse and scattered to permit substantiated calculation of the constants. Author
