Gas chromatographic conditions for the analysis of y-irradiated benzonitrile for cyanoaromatic products
In a. study of the y-radiolysis of benzonitrile, the three isomeric dicyanobenzencs, the three isomeric cyanobiphenyls, and the six isomeric dicyanobiphenyls (one cyano group per phenyl ring) were expected as radiolytic products, and hence, it was necessary to be able to analyze the y-irradiated benzonitrile for these cyanoaromatic compounds. A search of the literature did not reveal any information on specific conditions for the analysis of these compounds, and this paper describes the gas chromatographic (GC) conditions for the analysis of the cyanoaromatic compounds listed above.
NOTES
work with other Versamid goo columns in an effort to improve the resolution of the 2,3'-and 2,4'-dicyanobiphenyls and of the 3,3'-, 3,4'-, and 4,4'-dicyanobiphenyls did not produce any improvement in resolution. The GC comlitions that were found to be most satisfactory for the analysis of the test solutions of the dicyanobenzenes, cyanobiphenyls, and the clicyanobiphenyls are given in Table .
