PROCEDE DE DETERMINATION DE LA POLARITE CHIMIQUE D'UNE HUILE BRUTE ET DE SES FRACTIONS LOURDES

摘要

A process for determining the polarity of a crude oil or heavy fraction thereof in which the retention times are measured when a series of substances is contacted with a chromatographic column of crude oil, the retention times are measured when these substances are contacted with a chromatographic column of a second substance usually non-polar and the relative polarity of the oil determined from the times measured.
