Analysis of acenaphthylene in acenaphthene by hydrogenation-gas chromatography

Fundamental studies on hydrogenation of acenaphthene and acenaphthylene were carried out by means of micro hydrogenation-gas chromatography. Identification of the hydrogenation products of the compounds was made by both retention data of the associated gas chromatograms and IR spectra.By this method, the main impurity remaining even in purified acenaphthene by zone melting was proved to be acenaphthylene.This technique is very simple and rapid, and needs extremely small samples (0.10.2mg). Moreover it is generally applicable to structural characterization of the other unsaturated compounds.
