Two methods for separating the acid compound types of high-boiling petroleum distillates have been investigated. The first method utilized ferric chloride and ion-exchange resins, and the second method used gel permeation chromatography. Each method was found to have merits, and the two methods can be used to complement each other. The major compound types of a Wilmington 400 deg to 500 deg c acid concentrate have been separated and identified using these methods. Data from the separation schemes will aid in the characterization of the acidic materials.
