Kinematic viscosities of aqueous solutions of 2-amino-2-methylpropan-1-ol (AMP), 2-amino-2-methylpropane-1,3-diol (AMPD), or 2-amino-2-methylpropan-1-ol hydrochloride (AMP-HCl) and aqueous ternary solutions (AMP and AMPD) and (AMP and AMP-HCl) were measured in the molality range from 0 to 2.5 mol kg-1 (0.5 mol kg-1 intervals) and temperatures from 293.1 to 323.1 K (5.0 K intervals). The viscosity data were correlated with concentration and temperature by empirical equations with deviations up to 1.4 and 3.3% for binary and ternary aqueous solutions, respectively.
