BALDRICH FERRER, Carlos-A  e  NOVOA MANTILLA, Luz-Ángela. DETAILED CHEMICAL CHARACTERIZATION OF PETROLEUM MIDDLE FRACTIONS BY CHEMOMETRICS ANALYSIS OF THEIR ULTRAVIOLET SPECTRUM. C.T.F Cienc. Tecnol. Futuro [online]. 2007, vol.3, n.3, pp. 173-190. ISSN 0122-5383.

Chemometric analysis has been applied in this work to correlate ultraviolet spectra of middle distillates and vacuum gas oils with hydrocarbon type analytical data obtained by high resolution mass spectrometry.  The use of this methodology reduces the costs of chemical characterization of these types of petroleum fractions and may be applied to the characterization of diesel fuels and gas oils that are processed in fluid catalytic cracking or hydrotreating units.
