Abstract

Specific retention volumes (V_g), and relative formation constants (K′) are found for aromatic hydrocarbons, amines, and a series of β-ionyl compounds which are twisted diene systems. Di-n-butyi tetrachlorophthalate (DBTP) is used as the complexing (electron acceptor) stationary phase. Di-n-butyl phthalate (DNBP) and di-isooctyl phthalate (DIOP) were the reference phases. The order of relative formation constants for aromatic hydrocarbons and amines is demonstrated to be as expected. The β-ionyl compounds, however, give anomalous K′ values, due to severe out-of-plane deformation effects.
