Activity coefficients at infinite dilution have been determined by gas–liquid chromatography for nine hydrocarbons solutes in cyclopentanol, cyclohexanol, cycloheptanol, benzyl alcohol, and n-heptanol at 25 °C. Experimental results for cyclopentane and cyclohexane in cycloalkanols compare favourably with the values obtained by extrapolation to infinite dilution of activity coefficient data calculated from Benson et al.'s static (vapour–liquid equilibrium) measurements. Some characteristics of the solute–solvent interaction in the systems are discussed in light of statistical approaches (thermal and athermal contributions).

Five solvents of the β‐alkoxypropionitrile series have been studied by gas‐chromatographyin order to examine their potential usefulness as solvents for extractive distillation. Four isomers of C4‐olefin and a diene were used as solutes for the determination of activity coefficients at infinite dilution at 30°C. Relative volatilities were calculated for these solvents and compared with those for other commercial solvents used currently. Relative volatilities of seven C4‐hydrocarbons in two solvents were also studied and compared with the existing literature data for β‐methoxypropionitrile containing 5% antisolvent. The present g.c. studies show that besides the well‐studied β‐methoxypropionitrile, the second member of the series, β‐ethoxypropionitrile, also has the potential for use as a selective solvent.
