Executive summary:

The Henry's law constant (HLC) of m-cresol was measured with a column method at 25°C resulting in a HLC of 0.087 Pa m³/mol.

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):
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.
