PFT properties in the compressed liquid phase were determined for 2-amino-2-methyl-1-propanol (AMP) and AMP + water (at x1 ) 0.0480, 0.0736, 0.1188, and 0.1668) at temperatures from (313 to 363) K and pressures up to 24 MPa. A vibrating tube densimeter (VTD) was used to measure the densities. The classical calibration method of using two reference fluids (water and nitrogen) was used for the calibration of the VTD. The uncertainty of the measured densities was estimated to be ( 0.2 kg *m-3. The liquid densities of aqueous AMP solutions reported in this work were correlated using a six-parameter equation. Isothermal compressibilities and isobaric thermal expansivity are calculated using the six-parameter equation within uncertainties estimated to be ( 3 * 10-6 MPa-1 and ( 4 * 10-7 K-1, respectively. Also, the excess molar volumes were calculated for the mixtures using densities of AMP calculated with the obtained correlation and densities of water calculated with a reference equation of state. The uncertainty of the excess molar volumes was estimated to be ( 6 * 10-6 m3 * kmol-1.
