Аннотация:This work is devoted to further accumulation of data on key thermodynamic properties of esters: determination of low-temperature heat capacities and characteristics of the phase transitions crystal–liquid, extrapolation of vapor pressures to temperatures of triple points, Ttp, and 298.15 K and the establishment of the thermodynamic functions S°m(T) and for condensed and ideal gas states, including the functions of formation ΔfSmo(T), ΔfHmo(T) and ΔfGmo(T) at T = 298.15 K.
