Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0
at the temperature of:
20

Additional information

Based on the vapour pressure of the substance (1.5·10-6Pa (20°C)), SymHelios® 1031 can safely be considered as non-volatile. In addition, a calculation of Henry`s law constant at 2.37 10-4Pa m³/mol on the basis of the experimental determination of water solubility and vapour pressure, indicates that the substance does not volatilize from water or wet surfaces.
