Additional information

The Henry´s Law constant of Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts was determined by using EUSES v2.1 (Chemservice S.A., 2013). Henry´s law states that the solubility of a gas in a liquid solution at a constant temperature will be proportional to the partial pressure of the gas which is above the solution (Henry, 1803). Sometimes, the term “air/water partition coefficient” refers to the dimensionless Henry´s law constant (HLC) and therefore describes the ration of the equilibrium concentration of a dissolved substance in air and water. This parameter is calculated from temperature corrected experimental vapour pressure and water solubility. A Henry´s Law Constant of 97.2 Pa*m³/mol was calculated for Benzenesulfonic acid, di-C10-14-alkyl derivatives, calcium salts, related to 25 °C.
