A high-pressure flow-mixing isothermal calorimeter was used to determine the excess molar enthalpies of four binary systems for N,N-dimethylethanolamine + (methanol, ethanol, 1-propanol, and 2-propanol) at T = (298.2, 313.2, and 328.2) K and p = (0.1 and 10.0) MPa. The experimental data were correlated by the Redlich-Kister equation and three local composition models (Wilson, NRTL, and UNIQUAC).
