## Abstract Detailed investigation of solvent‐separated fractions of petroleum vacuum residues is necessary for understanding the separation mechanism using different solvents and to prepare better feedstocks for secondary conversion processes. The efficiency of different solvents to remove polars

## Abstract A new and simple quantitative structure-retention relationship (QSRR) was tested as a predictive model for adjusted retention times in complex petroleum condensate fractions. This relationship adopted the form of a non-linear collective retention-variables model. The adjusted retention
## Chromatographic analyses arc used to great advantage in cluantitatively determining lower boiling components of petroleum for which reasonably good rcsolution is yossil~lc. For petroleum fractions of broader range many devices have been used to allow a quantitative analysis. Examples are the us
