摘要: Abstract Vapor-liquid equilibrium data for the binary systems β-pinene + limonene and p-cymene were determined at atmospheric pressure in an Othmer still. Vapor pressures of pure components measured correlated with Antoine equation. Parameters Van-Laar, Margules, Wilson, NRTL UNIQUAC equations calculated aid a Nelder - Mead technique to minimize objective function based on total pressure. Predictions UNIFAC method also obtained.
