ABSTRACT
The pressure dependence of the molar volume of the 1,4-butanediol + 1-dodecanol system has been measured at 298.15 K for 0.1 e P/MPa e 40.0 and for the whole concentration range. All the results can be described by an equation with a single fitting parameter which takes a value similar to those obtained for non-hydrogen-bonded mixtures. The volumetric results at ambient pressure can be described by a lattice-fluid theory which incorporates the effect of the hydrogen bonds. The same theory is able to reproduce the compressibility of the pure components over the whole pressure range. However, it is not able to predict the compressibility of the mixtures nor the excess Gibbs energy.
