Activity coefficients at infinite dilution for 26 solutes (paraffins, cycloparaffins, olefins, aromalics, n. chloroparaffins, chloroform, tetrachloromethane, acetates, ketones, alcohols and nitriles) in five solvents containing two functional groups of the same nature were determined by gas-liquid chromatography. The solvents employed were hexanediol, nonanediol, hexanedithiol, dodecanediamine and dodecanedinitrile. The influence of the second functional group is suggested from both the absolute values of the activity coefficients as well as from the selectivity values of these solvents with respect to paraffin-aromatic separation.
