RETENTION INDEX SYSTEM, ADSORPTION CHARACTERISTICS, AND STRUCTURE CORRELATIONS OF POLYCYCLIC AROMATIC-HYDROCARBONS IN FUELS

Part of this work focuses on temperature programmed retention index as sessment of 70 polynuclear aromatic hydrocarbons (PAHs) using a methyl silicone capillary column. The use of the retention index presented he re offers a good possibility of identifying and determining PAHs in th e mass range discussed and to apply such conditions to the analysis of fuel and fuel deposits, Retention indices and vaporization enthalpy d ata of PAHs are linearly related to the molecular total energy. This p aper describes also a gas-chromatographic study of the adsorption of s ome PAHs on Carbopack.
