Thermodynamic properties of 2-methyl-5-phenylfuran-3-carboxylic
The temperature dependence of the saturated vapor pressure and the combustion energy of 2-methyl-5-phenylfuran-3-carboxylic acid were determined by experimental methods. Based on the obtained data, the values of the enthalpies of combustion and formation in the condensed state were calculated. The enthalpy of sublimation was recalculated to 298K. The additive Benson scheme is supplemented with new fragments for calculating the enthalpies of formation in the gaseous state. The possibility of using the Joback method to calculate the enthalpies of formation of aryl furans in the gaseous state is analyzed.
