Gas chromatographic study of the urea—Cetyl alcohol adduct and its components

Summary As part of the gas chromatographic study of inclusion compounds, the behaviour of cetyl alcohol (the guest component in the inclusion compound with urea) and its properties as a stationary phase were followed. Measurements were carried out over a temperature range of 40–100°C with a wide selection of substances including aliphatic and aromatic hydrocarbons, halocarbons, alcohols, esters, ethers, carbonyl compounds, amines and organic acids. The experimental retention data were interpreted from the point of view of possible interactions and the contributions from the individual intermolecular forces were evaluated. The results indicated that cetyl alcohol could be used as a stationary phase over a range of 50–90°C for rapid analysis of many non-polar, medium and strongly polar substances.Dedicated to the 70th birthday of ProfessorA.
