Density, Vapor Pressure, Enthalpy of Vaporization and Heat Capacity of (E)-Isobutyl Cinnamate

•Density of (E)-isobutyl cinnamate was measured and fitted linearly.•Vapor pressure of (E)-isobutyl cinnamate was measured by the ebulliometric method.•ΔvapH (298.15K) was calculated and its thermodynamic consistency was verified.•Heat capacity of liquid (E)-isobutyl cinnamate was measured and correlated. The density of (E)-isobutyl cinnamate at 297.95-535.20 K was measured using a capillary pycnometer and linearly related to temperature. The vapor pressure of (E)-isobutyl cinnamate at 420.15-570.05 K was measured by the ebulliometric method, and correlated by Antoine equation with an average relative deviation of 1.11%. The vaporization enthalpy ΔvapH (Tb) of (E)-isobutyl cinnamate at normal boiling point was obtained based on the Clausius-Clapeyron equation. The standard vaporization enthalpy ΔvapH (298.15 K) was calculated to be 73.67±0.5 kJ·mol−1 by Othmer's method and verified by the Corresponding State Group Contribution (CSGC) method. The heat capacities at saturation vapor pressure (CSL) of (E)-isobutyl cinnamate were measured at 298.15-533.15 K by an automatic calorimeter and correlated by a quadratic polynomial.
