Compressed liquid density measurements for {methylbenzoate + (cyclohexane or 1-hexanol)} binary systems

Densities of the binary systems {methyl benzoate + (1-hexanol or cyclohexane)} were measured over the full composition range from (278.15 to 358.15) K and pressures up to 60 MPa, as a part of a study on the interactions between MB and organic solvents provided with six atoms of carbon but different functional groups and structures. Experimental data were correlated with temperature and pressure using the TRIDEN-10 parameter equation. From these parameters, isobaric expansivity, isothermal compressibility, and internal pressure were calculated. The complex behavior of the derived excess properties was interpreted in terms of intermolecular interactions and structural effects between the system components.

Research highlights► (methylbenzoate + cyclohexane/1-hexanol) pressure–temperature –density–behavior. ► PVT data was measured using vibrating tube densimeter. ► Data was correlated using TRIDEN equation. ► Excess properties were analyzed as a function of pressure and temperature.
