Abstract A faster and accurate infrared method for estimating total aromatics in petroleum samples boiling in the kerosene range (140–250°C) was developed using pure aromatic concentrate from kerosene as reference material. The limitations of a synthetic mixture of pure compounds used as reference are also discussed. The accuracy of results is found to be dependent on the closeness of the average absorptivity at a characteristic wave number (1600 cm −1 ) of an unknown sample and kerosene used as reference. The results obtained from the proposed method on kerosene fractions of Bombay High are compared, as an illustration, with those obtained by FIA.
