EXCESS MOLAR VOLUMES OF SOME HYDROGEN-BONDED COMPLEXES AT 298.15 K AND THE APPLICATION OF THE ERAS MODEL

Excess molar volumes V-m(E) measured at 298.15 K are reported for sing le hydrogen bonded complexes involving propan-1-ol, di-n-propylamine, or propane-1-thiol + di-n-propyl ether, tri-n-propylamine, dipropyl su lfide, or heptan-4-one. Together with previously reported molar excess enthalpies (Letcher and Bricknell, 1996), the V-m(E) data have been u sed in the application of the ERAS model to mixtures involving assumed single hydrogen bonds (O-H ... O, O-H ... N, OH ... S, N-H ... O, N-H ... N, NH ... S, SH ... O, SH ... N, and SH ... S).
