Point-AHV Relationships

Critical Point- AH Relationships Estimation methods that use critical point data to estimate AHv have been reviewed in various accounts [1,5,6]. Usually, additional input such as boiling point data Tb and AHb or the acentric factor is required. The advantage of these methods is that they allow temperature-dependent estimation. One such method is presented in further detail in Section 8.5. 

Most of the structure-A//v relationships have been developed for either AHv at 25°C or for the normal boiling point enthalpy, AHvb. Relationships of both types are discussed below.
