Excess molar volumes of (an alkanol plus a branched chain ether) at the temperature 298.15 K and the application of the ERAS model.

The results are explained in terms of the strong self-association of the alkanols, the specific interaction between the alkanol, and the ether molecules and packing effects upon mixing. The experimental V-m(E) results presented here, together with the previously reported data for the molar excess enthalpy H-m(E), has been used to test the Extended Real Associated Solution (ERAS) model.961410 bytesapplication/pdfenCopyright: 1997 Elsevier Science BVExcess molar volumesAlkanolBranched chain etherExtended real associated solution modelERASPhysical chemistryChemical engineeringArticleLetcher, T., & Govender, P.
