Vapor−Liquid Equilibrium for Carbon Dioxide + 1-Butanol at High Pressure

This is the authors' abstract. We don't add key points for this paper.

Vapor−liquid equilibria and saturated densities for carbon dioxide + 1-butanol at high pressures were measured at 313.15 K including in the vicinity of the critical region with the static-circulation apparatus. The present experimental vapor−liquid equilibrium results significantly differ from the values reported by King et al., but agree with those of Jennings et al. The results were correlated with various equations of state.
