| Abstract
| - The vapor−liquid equilibria for water + 2-propanol, water + 2-butanol, and water + 2-pentanol systems weremeasured at (523 to 573) K and (3.30 to 11.48) MPa by a flow method. The vapor−liquid equilibrium data forthe water + 2-propanol system at (548 and 573) K were compared with the literature data to confirm the validityof the experimental apparatus and procedure. The phase behavior was elucidated by changing the temperaturesand the carbon number of the secondary alcohols. The experimental data obtained in this work were correlatedby a modified Soave−Redlich−Kwong (MSRK) equation of state. An exponent-type mixing rule was applied tothe energy parameters in the equation of sate. The correlated results are in good agreement with the experimentaldata.
