摘要: Abstract The densities, viscosities, and conductivities of the ternary solutions [N-EMP]Br (N-ethyl,methyl-piperidinium bromide) + [N-PMP]Br (N-propyl,methyl-piperidinium bromide) + H2O, [N-EMP]Br + [N-BMP]Br (N-butyl,methyl-piperidinium [N-PMP]Br + [N-BMP]Br + H2O their binary subsystems at (293.15, 298.15, 303.15, 308.15) K atmospheric pressure were measured. equations for prediction density, viscosity, conductivity mixed electrolyte extended to predict related properties ionic liquid solutions. predicted values agree well with experimental data, indicating that examined aqueous piperidinium-based ILs can be from corresponding data equal strength by using these equations. In addition, equation Patwardhan Kumar, Hu’s equation, Young’s rule provide better predictions than simple
