Abstract
Excess enthalpies of six binary mixtures between methyl methylthiomethyl sulfoxide (MMTSO) or dimethyl sulfoxide (DMSO) and one of the dialkylethers (diethylether, ethylpropylether or dipropylether) have been determined at 298.15 K. All the mixtures observed showed positive excess enthalpies over the whole range of mole fractions and miscibility gaps. The mutual solubilities decreased with the increase in size of the alkyl radicals. Excess enthalpies determined at saturated mole fractions also decreased with the increase in size of the alkyl radicals. The enthalpies and entropies of transfer between conjugate mixtures were determined. The excess enthalpies of the mixtures containing DMSO were larger than those containing MMTSO. A comparison of the results with those for six binary mixtures containing a cyclic ether is made.
