Density and viscometric study of binary liquid mixtures of morpholine with some aromatic hydrocarbons at temperatures 303.15, 308.15 and 313.15 K

摘要: Abstract The experimental data of densities and viscosities the binary mixtures morpholine with benzene, toluene, m-xylene mesitylene have been reported over whole composition range at (303.15 to 313.15) K normal atmospheric pressure. Experimental on density viscosity used derive excess properties like molar volumes V E , deviations ( Δ η ) Gibbs energy activation for viscous flow (GE) as a function composition. correlated two body empirical equations Grunberg–Nissan, Dolezalek–Schulze, Tamura–Kurata, Katti–Chaudhri three McAllister's equation. Interaction parameters D12, G12, T12, Wvis/RT calculated. determined values VE, Δη GE were fitted Redlich–Kister-type polynomial variation these temperature are discussed in terms intermolecular interactions between unlike molecules.
