Vapor-Liquid-Equilibria of Cyclohexanol with Carbon-Dioxide, Ethane, or Nitrogen at Elevated Pressures
Vapor-liquid equilibrium (VLE) data were measured for the binary systems of cyclohexanol with carbon dioxide, ethane, or nitrogen at temperatures from 333.15 K to 453.15 K and pressures up to 190 bar. The saturated vapor compositions were correlated with the density of the light components. Henry’s constants of the gases dissolved in cyclohexanol were calculated with the aid of the Krichevsky-Ilinskaya equation. The new VLE data were also correlated by the Peng-Robinson and the Patel-Teja equations of state. In general, the Patel-Teja equation incorporating the one-fluid, two-parameter van der Waals mixing rule yielded the best representation.
