Lydersen method
From Wikipedia, the free encyclopedia
The Lydersen method[1] is a group contribution method for the estimation of critical properties temperature (Tc), pressure (Pc) and volume (Vc). The Lydersen method is the prototype for and ancestor of many new models like Joback,[2] Klincewicz,[3] Ambrose,[4] Gani-Constantinou[5] and others.
The Lydersen method is based in case of the critical temperature on the Guldberg rule which establishes a relation between the normal boiling point and the critical temperature.
