In the present study, the density (ρ) and dynamic viscosity (η) of binary liquid mixtures such as glycerol (GLY) + isomers of butanol (1-butanol (1-BU), 2-butanol (2-BU), and tert-butanol (T-BU)) were experimentally measured as a function of glycerol mole fraction at T = (293.15 to 318.15) K and a pressure of 0.1 MPa. Using these experimental data, the deviation in viscosity (∆η), molar volume ( \({V}_{\text m}\) ), excess molar volume ( \({V}_\text{m}^\text{E}\) ), apparent molar volumes ( \({V}_{\text {m},\varnothing ,1}\) and \({V}_{\text {m},\varnothing ,2}\) ), partial molar volumes ( \({\overline{V} }_{\text {m},1}\) and \({\overline{V} }_{\text {m},2}\) ), and excess partial molar volumes ( \({\overline{V} }_{\text {m},1}^{\text E}\) and \({\overline{V} }_{\text {m},2}^{\text E})\) values were calculated. The observed \({V}_\text{m}^\text{E}\) and ∆η results were associated with the Redlich–Kister (R-K) model. Further, the \({V}_\text{m}^\text{E}\) values were interpreted using the Prigogine–Flory–Patterson (PFP) model. The obtained \({V}_\text{m}^\text{E}\) showed a negative deviation, and ∆η showed a positive deviation over the entire composition range of glycerol. The derived parameters in binary mixtures are affected by H-bonding. Moreover, the development of new H-bonding interactions between unlike molecules was further described using 1H-NMR spectroscopy studies.
