EXCESS PROPERTIES FOR 1-BUTANETHIOL + NORMAL-HEPTANE, CYCLOHEXANE, BENZENE, AND TOLUENE .1. EXCESS MOLAR VOLUMES AT 283.15-K AND 298.15-K

This paper reports densities and excess molar volumes at 283.15 and 298.15 K, at atmospheric pressure, for binary mixtures of 1-butanethiol + n-heptane, cyclohexane, benzene, and toluene. The excess molar volumes are less than 0.607 cm3mol-1, or 0.56% of the mixture molar volume. The excess molar volumes Increase with increasing temperature for 1-butanethiol + n-heptane; they decrease with Increasing temperature for the other three systems. Excess molar volumes for 1-butanethiol + aromatic systems are smaller than for parafflnic systems, with the maximum values for toluene being 0.007 cm3 mol-1. © 1990, American Chemical Society.
