Abstract
The major acidic compounds types in ten high-boiling crude oil distillates were identified as carboxylic acids, phenols, carbazoles, and amides. Acids from crude oils having different geological characteristics were separated using a standardized separation scheme and the compositional results were compared. The separation scheme involved the use of gel permeation, adsorption, and thin-layer chromatography. Quantitative infrared analysis was used to estimate the relative amounts of acidic compound types. The structures of the acidic compounds were examined in detail using mass, fluorescence, and nuclear magnetic resonance spectrometry.
