Vapour pressures and excess Gibbs energy of ethylbenzene-cyclooctane binary mixtures

Isothermal vapour-liquid equilibrium data at 343.15, 353.15 and 373.15 K for ethylbenzene + cyclooctane mixtures are reported. Use has been made of an ebullioneter which allowed sampling from both phases in equilibrium. ent GE expressions suitable for correlation of these data were tested. The results evidenced a positive deviation from ideality of the system.
