Abstract

Porapak T is a new separation material suitable for the selective separation of aromatic hydrocarbons and their partially hydrogenated derivatives by chromatography in both a flat bed (thin-layer chromatography) and a columnar (liquid chromatography) arrangement. The differences in retention in the system Porapak T-non-polar solvent are analytically significant and enable substances that differ in structure by only one double bond to be separated. The regularities ascertained are obviously of general applicability and may be utilized also for substituted analogues.
