- Abstract
- Excess molar enthalpies, H-m(E), were determined as a function of molar fraction at 308.15 K and at atmospheric pressure for the binary mixtures containing dimethyl sulfoxide with ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, poly(ethylene glycol)-200, poly(ethylene glycol)-300, poly(ethylene glycol)-400, and poly(ethylene glycol)-600. All curves are negative over the entire composition range with minima ranging from -430 J.mol(-1) (propylene glycol) up to -1080 J.mol(-1) (poly(ethylene glycol)-600). The results were correlated using the Redlich-Kister polynomial, and the adjustable parameters were obtained by the least-squares method. The dependence of H-m(E) on mixture composition is qualitatively discussed in terms of molecular interactions. (literal)
