The measurement of organic complex formation constants by gas–liquid chromatography

Abstract

The g.l.c. technique has been employed to measure formation constants of, and thermodynamic parameters for, complexes formed between benzene, toluene, and the xylenes and di-n-propyl tetrachlorophthalate in the temperature range 60–80°C. Infinite-dilution activity coefficients for the aromatic compounds in squalane are also obtained and interpreted. The method is shown to be competitive with existing techniques, and to offer a number of important advantages for studies in organic media.
