Acentric factor
Definition
Acentric Factor is defined as the value of reduced saturated vapor pressure at the reduced temperature of 0.7. It is calculated based on the following formula.
Estimation Method
- MolInstincts: The Property value is estimated by the combination of fundamental thermodynamic theories, modern modeling approaches, QSPR (quantitative structure-property relationships) methods, and ANN (Artificial Neural Network) with over fitting prevention algorithm, utilizing the quantum chemical calculations results and molecular descriptors. The estimated value is finally determined after manual inspection.
