Excess molar volumes (VmE) were calculated from density values and correlated with Redlich-Kister polynomial equation. Partial molar volumes at infinite dilutions (Vm,i�) of the ILs and methanol were determined from the Redlich-Kister coefficients. For all the studied systems, the VmE is negative over the entire composition range. The VmE and Vm,i� are interpreted in terms of intermolecular interactions in the binary mixture. Density functional theory has been used to investigate the interactions between methanol and the studied ILs. © 2015 Elsevier B.V. publisher: Elsevier date: 2015 type: Article type: PeerReviewed identifier: Gonfa, G. and Bustam, M.A. and Muhammad, N. and Ullah, S.
