METHODS FOR ANALYSIS OF POLYPHENYL REACTOR COOLANTS
Analytical methods developed for the study of irradiatod and unirradiated polyphenyl reactor coolants are explained in detail. Gas chromatographic methods are described for the determinations of biphenyl, o-, m-, and p-terphenyl, benzene, toluene, and ethylbenzene in irradiated polyphenyl coolants. Other low-boiling components are also determined collectively by a gas chromatography method. An ultraviolet spectroscopic method is given for the determination of triphenylene (a radiolytic decomposition product of terphenyls). A low-voltage mass spectroscopic technique is described for a "group-type" analysis of the higher boiling decomposition products of pelyphenyl coolants. Masses are assigned to phenyl-, alkyl-, and hydro-derivatives of polyphenyls, triphenylenes, and phenanthrenes. Methods are also reported for the determination of gross properties such as high-boiler content of coolants, average molecular weight, carbon and hydrogen content, and olefin (unsaturation) content by ozone absorption.
