Abstract

High performance liquid chromatography in the reversedphase mode was used for the analysis of coal liquefaction materials. The chromatographic system used was optimized for separation of the more polar, heteroatom-containing components. A model study of a wide variety of compounds was undertaken in which capacity factors were correlated to a set of structural parameters in order to gain insight into the retention mechanism. Reversed-phase separation of a model mixture as well as separation of boiling fractions of hydrotreated and nonhydrotreated process recycle solvents are compared.
