Fishtine Constant

Fishtine Constant
Definition:	Empirical constant K_F for prediction of the enthalpy of vaporization ΔH_b at the boiling point according to the following law: ΔH_b = K_F T_b R (36.64 + ln T_b), where R = gas constant and T_b = boiling point in Kelvin. The Fishtine constant includes effects such as van-der-Waals, dipole-dipole and hydrogen bonding interactions.
Units:	dimensionless
Symbol:	K_F
Scope note:	Organic compounds
Translation:	DEFishtine-Konstante FRConstante de Fishtine
