Volumetric and viscometric properties of binary and ternary mixed alkylamine solutions of 1-dimethylamino-2-propanol, benzylamine and water from 293.15 K to 333.15 K

In this study, the densities and viscosities of the binary solutions 1-dimethylamino-2-propanol (1DMA2P) + H 2 O, benzylamine (BZA) + H 2 O, 1DMA2P + BZA and ternary solution 1DMA2P + BZA + H 2 O were measured at T  = (298.15−333.15) K. Furthermore, the volumetric and the viscometric properties including the excess molar volume, partial molar volume, apparent molar volume, limiting apparent molar volume, viscosity deviation, excess Gibbs energy of activation for viscous fluid and Grunberg-Nissan interaction parameters were obtained in terms of experimental data, respectively. The excess molar volumes of binary and ternary solutions were fitted by the Redlich-Kister equation and Cibulka equation, besides, the viscosity and viscosity deviation of binary solution were correlated by using the Grunberg-Nissan equation and Redlich-Kister equation. Moreover, the intermolecular interactions were analyzed based on the volumetric and viscometric properties of solutions.
