ABSTRACT
Isothermal vapor liquid equilibrium (VLE) data were measured for the binary systems of nitrogen with 2-hexanol, 2-heptanol, or 2-octanol at temperatures from 333.15 to 393.15K 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.
