Results and discussion

Henry's Law constant H
H:
2 Pa m³/mol
Temp.:
25 °C
Atm. press.:
1 atm

Any other information on results incl. tables

However, the estimated value of around 2 Pa/ mol * m3 (at 25°C) may not be appropriate since the vapour pressure used may reflect large contributions from the volatile impurities tributyl phosphate and phenol.
