Abstract
N-ethylpiperazine (NEP) is an important intermediate in the synthesis of drugs and dyes. Its fundamental data are lacking. The saturated vapor pressure of NEP and the VLE data for water-NEP system at pressure of 101.3 una have been measured by using an improved Rose still. The VLE data have been tested for thermodynamics consistency and correlated satisfactorily with Wilson equation. The average absolute deviations are △T= 0.14K, △y1, = 0.0022. The VLE for piperazine(1)-NEP(2) system at 101.3 kPa has been predicted by using modified UNIFAC model (Ⅰ) and modified UNIFAC model (Ⅱ).
