摘要：

Vapor pressures of bis(hydroxyethyl)piperazine (BHEP) and tris(hydroxyethyl)ethylenediamine (THEED) were measured in the temperature ranges of (412.65 to 507.15) K and (372.55 to 472.35) K using the static and gas saturation techniques, respectively. The experimental data are well represented by the modified Antoine and the integrated Clausius-Clapeyron equations, and their coefficients are reported. The enthalpies of vaporization were found to be (62.76 +/- 5.33) and (89.96 +/- 3.91) kJ/mol for BHEP and THEED, respectively.
