A review of analytical methods for the quantification of aromatics in diesel fuels

Report no. 94/58: The definition of "aromatics" in diesel fuel has caused difficulties, both within the oil industry and amongst other interested parties. By virtue of the boiling range of the fuel, the majority of its hydrocarbons will have between ten and twenty carbon atoms. T

his means that any molecule considered aromatic may also have a "nonaromatic" component that is greater than the aromatic portion. The level of aromatics that is measured is therefore dependent on the technique used. This report summarizes the various analytical procedures currently available for the determination of diesel fuel "aromaticity".
