Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
2 370
at the temperature of:
20 °C

Additional information

An experimental determination of HLC has been carried out by Munz (1987), who determined H = 2370 Pa.m3/mol at 20°C. A supporting value of 2990 Pa.m3/mol at 25°C can be found in a handbook.
