✦ Synopsis

Measurements of speeds of sound u have been made in binary mixtures of 1,1,2,2-tetrachlorethane (CHCl2CHCl2) with anisole (C6H5OCH3), 1,4-dioxane (C4H8O2), methylethylketone (CH3COC2H5), and pyridine (C5H5N) at T = 303.15 K. Values of u have been used to calculate the apparent excess speeds of sound Du and the isentropic compressibilities kS for these mixtures. The excess isentropic compressibilities k E S have also been calculated from the values of kS. The k E S have been found to be highly negative for {xCHCl2CHCl2 + (1x)CH3COC2H5}, and very slightly negative for {xCHCl2CHCl2 + (1x)C4H8O2}. The k E S is very slightly negative at low x, and very slightly positive at higher x for {xCHCl2CHCl2 + (1-x)C6H5OCH3}. The k E S is also very slightly negative for {xCHCl2CHCl2 + (1-x)C5H5N} at low x and, compared with {xCHCl2CHCl2 + (1x)C6H5OCH3}, the k E S is more positive for {xCHCl2CHCl2 + (1x)C5H5N} at higher x. Values of k E S for the various systems have been discussed in the light of interactions between the components.
