Key result
H:
780.7 Pa m³/mol
Temp.:
20 °C
Atm. press.:
1 013 hPa
Conclusions:
2-chlorotoluene is characterized by a calculated Henry's Law Constant of 780.7 Pa m³/mol at 20 °C.
Executive summary:

Henry's law constant at 20 °C for 2-chlorotoluene was calculated from the experimentally determined vapour pressure (382.4 Pa at 20 °C) and water solubility (62.0 mg/L at 20 °C) considering the molecular weight (126.58 g/mol).
Henry's law constant (20 °C): 780.7 Pa m³/mol (Currenta, 2009).
