Vapor pressures of the biologically and industrially relevant amines 2-phenylethan-1-amine, 2-amino-1-phenylethanol, α-(methylaminomethyl)benzyl alcohol, 1-phenylmethanamine, and N,N-diethylundecan-1-amine were measured via the transpiration method. Pure-component parameters for the thermodynamic model PC-SAFT were fitted to these vapor pressures and to liquid densities. The pure-component parameters were validated with measured liquid densities of binary mixtures dimethylsulfoxid + 4-(2-aminoethyl)phenol, dimethylsulfoxid + 2-amino-1-phenylethanol, dimethylsulfoxid + α-(methylaminomethyl)benzyl alcohol, and dimethylsulfoxid + 1-phenylmethanamine at 0.102 MPa and temperatures from 298.15 to 343.15 K at different amine mass fractions. Solid–liquid equilibria at 0.1 MPa were measured in binary mixtures of α-(methylaminomethyl)benzyl alcohol + water and 4-(2-aminoethyl)phenol + water at 298.15 and 308.15 K. Finally, the presence of liquid–liquid phase separation for these systems was qualitatively predicted using PC-SAFT based on the solid–liquid equilibria only and validated for the system α-(methylaminomethyl)benzyl alcohol + water by experiments at 293.15 and 323 K at 0.1 MPa.
