ABSTRACT
Densities (q), speeds of sound (u) and refractive index (nD) for the binary mixture of 1-Butyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide [Bmim] [NTf2] with N-Vinyl-2-pyrrolidinone (NVP) over the entire range of composition and at temperatures ranging from 298.15 K to 323.15 K at 0.1 MPa pressure, are reported in this investigation. From the experimental data, excess molar volumes (Vm E ), excess molar compressibilities (js E), excess molar isentropic compressibilities (Ks,m E ), excess speeds of sound (uE), and deviation in molar refraction (DRm) are calculated and fitted with Redlich-Kister polynomial smoothing equation. Excess molar volumes are predicted through PFP theory and the results are compared with experimental findings
