Description of key information
The experimentally determined Henry's law constant for m-cresol is 0.087 Pa*m³/mole at 25°C.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.087
- at the temperature of:
- 25 °C
Additional information
The distribution of m-cresol between aqueous solution and air is described by the Henry’s law constant.
A thermodynamic method was used to determine the Henry's law constant of m-cresol. At 25°C a value of 0.087 Pa*m³/mol was obtained. This value indicates a low volatility for m-cresol from aqueous solution.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
