Abstract

Impurities present in commercially available naphthalene, fluoranthene and anthracene have been concentrated by zone melting and further evaporation of their extracts in chloroform, and identified by gas chromatography performed on CGC-FID and CGC-MS apparatuses. Quantitative contents of fourteen, eight and twelve impurities detected in naphthalene, fluoranthene and anthracene, respectively, have also been determined.
