Iomex, an aromatic rich concentrate from kerosene feedstock is a potential source for production of naphthalene which has a variety of industrial applications. Four analytical procedures were standardized for compositional study of iomex according to chemical class wise. Hydrocarbon group type separation (saturates, mono-and diaromatics) and quantitation was reported using column chromatography, gas chromatography, high performance liquid chromatography and mass spectrometry. Data generated by these techniques are in good agreement with each other. A diaromatic fraction containing naphthalene and its precursors was studied in detail by gas chromatography mass spectrometry (GC-MS). Capillary GC could resolve each and every component of the diaromatic fraction, whereas quantitation and characterization of 27 components were obtained by mass spectrometry.
