Popis: The density (ρ) and kinematic viscosity (v) data of polyethylene glycol 300 (PEG) + N, N-Dimethylformamide (DMF) binary mixture were determined under atmospheric pressure and six temperatures of T = (293.15–318.15) K. From these experimental results, the thermodynamic parameters like excess molar volume (VmE), apparent molar volume (Vφ,1 and Vφ,2) and partial molar volume (V1‾ and V2‾), viscosity deviation (Δη) and excess Gibbs activation free energy (ΔG*E) were systemically counted, in which the standard deviation between the experimental and calculated data was estimated by fitting the Redlich-Kister formula. The intermolecular interaction of DMF with PEG was analysed by FTIR and UV-vis spectral technologies.
