Separation of monosubstituted phenols by gas-liquid chromatography.

The factors influencing the separation of monosubstituted phenols on silicone oil, poly(ethylene glycol) (1500), Apiezon L + Bentone 34, squalane, Versamide and diethylhexyl sebacate are discussed. Specific retention volumes, height equivalent to a theoretical plate and thermodynamic quantities are reported. Diethylhexyl sebacate and Versamide are selective for quantitative separation of all the isomers studied.
