Description of key information
Using the representative structures of "reaction products of alcohols, C14-18, C18 unsat., esterified with phosphorus pentoxide and salted with amines, C12-14,-tert-alkyl", both prediction tools give an "incomplete result".
Calculation with EUSES 2.1: 0.944 Pa*m³/mol
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.944
- at the temperature of:
- 25 °C
Additional information
The Henry´s Law constant of "Reaction products of alcohols, C14-18, C18 unsat., esterified with phosphorus pentoxide and salted with amines, C12-14,-tert-alkyl" was determined by using EUSES v2.1. 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 ratio of the equilibrium concentration of a dissolved substance in air and water. This parameter is calculated based on temperature-corrected experimental vapour pressure and water solubility. A Henry´s Law Constant of 0.944 Pa*m³/mol was calculated for "Reaction products of alcohols, C14-18, C18 unsat., esterified with phosphorus pentoxide and salted with amines, C12-14,-tert-alkyl", related to 25 °C.
