Abstract
Gel permeation chromatography (gpc) was used to separate the components of an acid concentrate. This concentrate was prepared from the 400 deg. to 500 deg. C distillate of Wilmington (California) Petroleum. The separation was made with a cross-linked polystyrene gel, using methylene chloride as a solvent; and the fractions obtained were characterized by infrared spectra and by molecular weight data. A carboxylic acid fraction obtained was essentially free of phenolic and nitrogen-containing compounds. Results indicate that molecular association of some compound types is responsible for the separation.
