A protocol for correcting experimental fusion enthalpies to 298.15 K and it's application in indirect measurements of sublimation enthalpy at 298.15 K

A protocol for adjusting fusion enthalpies as a function of temperature is described. The protocol combines two simple relationships previously proposed to adjust sublimation and vaporization enthalpies with temperature. This new protocol provides improved accuracy and precision relative to the other theoretical and empirical methods tested. Experimental fusion and vaporization enthalpies measured at different temperatures are adjusted to 298.15 K. Their sum when compared to experimental sublimation enthalpy values at 298.15 K deviates from the experimental values by approximately ±4 kJ for the 117 compounds used in the database. This protocol appears to function successfully for enthalpies measured from 200 to 500 K.
