The functions HE and VE have been measured at 303.15 K. for the mixtures of methanol with (±), (+) and (-) octan-2-ol. As expected, it is found that the excess functions are identical for the optical isomers, within experimental error. The volume of mixing of the ( +) and ( —) isomers is also found to be equal to zero. Plus
