Kow constant

The n-octanol-water partition coefficient, Kow is a partition coefficient for the two-phase system consisting of n-octanol and water. Kow is also frequently referred to by the symbol P, especially in the English literature. It is also called n-octanol-water partition ratio. Kow serves as a measure of the relationship between lipophilicity (fat solubility) and hydrophilicity (water solubility) of a substance. The value is greater than one if a substance is more soluble in … WebOpeningstijden Centraal Kantoor: 08.00 – 17.00 uur. Postadres: Postbus 7035. 4330 GA Middelburg.
