Title: Chromatographic techniques used in the characterization of high-boiling petroleum distillates
Abstract: Systematic application of ion-exchange, coordination-complex, and adsorption chromatography was used to separate high-boiling distillates into acid, base, neutral nitrogen, saturate, and aromatic fractions. The acid, base, and neutral nitrogen fractions were further separated by adsorption, gel-permeation and thin-layer chromatography to give concentrates that were amenable to detailed characterization of the compound types present in each fraction. Each separation step was designed to take advantage of a different molecular property, such as adsorptivity, reactivity, or molecular size, of the compound types in the distillates and to provide valuable analytical data on the composition of the distillate. These techniques separate the high-boiling distillates without causing thermal degradation or chemical alteration.
