- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)

- other:
- Remarks:
- calculation
- Key result
- H:
- 0.26 Pa m³/mol
- Temp.:
- 20 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- other: Henry's law constant was calculated from the vapour pressure and the water solubility. Ethyl lactate is miscible with water. Accordingly, the solubility can be equated with the molarity of pure ethyl lactate.
- Conclusions:
- Simple calculation of vapour pressure divided by aqueous solubility gives a Henry's law constant of 0.26 Pa × m³/mol for ethyl (S)-lactate.
- Executive summary:
Henry's law constant was calculated from the vapour pressure and the water solubility. Ethyl (S)-lactate is miscible with water. Accordingly, the solubility can be equated with the molarity of pure ethyl (S)-lactate.
