Measurement and correlation of vapor–liquid equilibrium data for binary systems composed of camphene, (+)-3-carene, (-)-β-caryophyllene, p-cymene, and α-pinene at 101.33 kPa

•VLE of binary systems of camphene + (-)-β-caryophyllene/p-cymene/ α-pinene and α-pinene + (+)3-carene/(-)-β-caryophyllene.•VLE data were measured by a modified Ellis equilibrium still for high boiling-points and high viscosities.•The VLE experimental data were correlated by the NRTL, Wilson, and UNIQUAC models.•Comparisons between the experimental data and calculated values were performed.
