Abstract

Excess molar volumes of V E of 2,3-butanediol +water were measured at p=O.l MPa with a faithful copy of the vibrating tube densimeter DMA 602 from Anton Paar. All binary mixtures were measured at the temperatures (308.2, 313.2, and 318.2) K Values of V E are negative for all the mixtures studied over the whole concentration range and for all temperatures. Results were correlated by polynomial equations of Redlich and Kister. In this paper, densities and molar excess volumes of binary (2,3-butanediol + water) systems in the temperature range of 308.2 K to 313.2 K at atmospheric pressure are reported. The measurements are part of a long-term study to examine the dependence of excess volumes on temperature. In the earlier papers [1,2] extensive database on the thermodynamic interactions in binary mixtures of 2,3-butanediol with water was presented. The aim of this work is to provide a set of values for the characterization of the molecular interactions of these mixtures and to examine the effect of the size of alkyl group of the diol.
