ABSTRACT

Experimental measurements and modelling of the density and viscosity of binary solutions of imidazole, 2-methylimidazole, 2,4,5-trimethylimidazole and 1,2,4,5-tetramethylimidazole with water have been conducted. Parameterization of viscosity data was conducted using a NRTLmodel, with AARD of 1% for imidazole, 0.8% for 2-methylimidazole, 3% for 2,4,5trimethylimidazole and 5% for 1,2,4,5-tetramethylimidazole. The density correlations represent the experimental data for imidazole solutions with AARD of 0.1% for all four imidazoles.
