Determination of Gasoline Properties by Fourier Transform Infr ared Spectroscopy / 分析化学

ABSTRACT

Combined with the partial least square regression, the oc tane number (RON), density, temperature evaporate (50%,90%), aromatics and olefi n concentration of gasoline were determined by the Fourier transform infrared spe ctroscopy at the wavenumber region of 1550～660cm－1. The experimenta l results showed that the actual values measured by the standard method were agre e with the prediction values by the proposed method.
