H. Piekarski et al., SOME PHYSICOCHEMICAL PROPERTIES OF AQUEOUS-SOLUTIONS OF ISOMERIC BUTANEDIOLS, Physics and chemistry of liquids, 30(4), 1995, pp. 195-207
Density, viscosity, electric permittivity and refractive indices for m
ixtures of water with four isomeric butanediols were measured over the
whole composition range at 298.15K. From these data the excess molar
volumes, apparent and partial molar volumes of butanediols and water,
the excess electric permittivity and Kirkwood's correlation factor for
investigated mixtures were calulated. Analysis of the results obtaine
d showed that although the investigated butanediols exhibit their indi
vidual features in the mixtures with water, there is a substantial sim
ilarity in the behaviour of butane-1, 2-diol and butane-2,3-diol. The
analogous similarity, but to a lower extent, is also observed in the c
ase of the other pair of butanediols, i.e. butane-1,3-diol and butane-
1,4-diol which have their apolar fragments shielded by the hydroxyl gr
oups.
