Resumen: In this paper, we report densities at 303.15 and 323.15 K and at atmospheric pressure (p = 0.1 MPa) of the binary mixtures containing dimethyl disulfide and a linear alkanol (methanol, ethanol, 1-propanol or 1-butanol). The isothermal vapor–liquid equilibrium for these systems was also determined at the same temperatures while the pressure range for vapor–liquid equilibrium measurement depends on both the mixture and temperature considered. The vapor–liquid equilibrium data were found to be thermodynamically consistent. From these data experimental excess volumes and excess Gibbs functions were obtained and correlated with composition using the Redlich–Kister polynomial expansion and the Wilson equation, respectively. The values of both excess properties were positive. The excess volumes, unlike the excess Gibbs functions, increase with the length of the n-alkanol chain.
