摘要：The density and the heat capacity of (E,E)-methyl sorbate (MS) were measured from 286.35 to 433.25 K using a pycnometer and an adiabatic calorimeter, respectively. The saturated vapor pressure of MS was determined by the ebulliometric method from 344.95 to 455.15 K and correlated by the Antoine equation with an average relative deviation of 1.68%. The enthalpy of vaporization of MS at the normal boiling point was figured out to be 44.29 kJ mol-1 according to the Clausius-Clapeyron equation. Based on the Othmer method, the standard enthalpy of vaporization of MS was obtained using three substances as a reference, and the calculated results were further verified by the Watson relation and the Clarke-Glew equation.
