Excess volumes for binary mixtures of n-alkanes + cyclohexane at 298.150 K by continuous dilution dilatometry

Abstract

The excess volumes of binary mixtures of n-pentane, n-hexane, n- heptane, n-octane, n-nonane and n-decane+cyclohexane were measured at 298.150 K with a continuous dilution dilatometer. The excess volumes were positive with the exception of mixtures of n-pentane with cyclohexane for which values were negative at all concentrations. The results have been compared with those published recently from data obtained in three systematic studies involving pycnometry, a vibrating tube densimeter and a semi-continuous dilatometer.
