Vapor–liquid equilibria for nitrogen with 2-propanol, 2-butanol, or 2-pentanol binary systems

Isothermal vapor–liquid equilibrium (VLE) data were measured for the binary systems of nitrogen with 2-propanol, 2-butanol, or 2-pentanol at temperatures from 333.15 to 393.15 K and pressure up to 100 bar. Henry's constants of nitrogen in these three sec-alcohols were determined by using the Krichevesky–Ilinskaya equation. The experimental VLE data were also correlated by the Peng–Robinson and the Patel–Teja equations of state with various mixing rules.
