Abstract

The heat of mixing H^E for N,N-Diethylethanolamine(DEEA), 1-(2-hydroxyethyl) piperazine(HEPZ) in water were measured with C-80 calorimeter at two different T=(303.15, 323.15)K and over the entire range of mole fractions. The experimentally measured H^E values are correlated as a function of mole fractions using the Redlich-Kister (RK) equation. And the nonrandom two-liquid (NRTL) parameters were simultaneously fitted using VLE and H^E data with good agreement with experimental data.
