- Boiling pt.:
- 122 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- other: Temperature at which an 88 % aqueous solution starts to boil. During boiling, temperature will increase due to changing composition of the solution (evaporation of water).
- Boiling pt.:
- ca. 204.2 °C
- Atm. press.:
- ca. 1 013 hPa
- Remarks on result:
- other: QSAR calculation: U.S. EPA EpiWin v1.4.1
- Conclusions:
- The boiling point of crystalline lactic acid is 122 °C at 15 mmHg (= 20 hPa). Concentrated aqueous solutions of lactic acid have boiling ranges between 120 and 130 °C. The boiling point of pure lactic acid at atmospheric pressure is estmated to be 204.2 °C (QSAR calculation).

Description of key information
The boiling point of crystalline lactic acid is 122 °C at 15 mmHg (= 20 hPa). Concentrated aqueous solutions of lactic acid have boiling ranges between 120 and 130 °C. The boiling point of pure lactic acid at atmospheric pressure is estimated to be 216.6 °C (QSAR calculation).

Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 216.6 °C
Additional information
The boiling point of crystalline lactic acid is 122 °C at 15 mmHg (= 20 hPa). Concentrated aqueous solutions of lactic acid have boiling ranges between 120 and 130 °C. The boiling point of pure lactic acid at atmospheric pressure is estimated to be 216.6 °C (QSAR calculation). The latter is considered to be the most reliable value, in view of the substance properties (polymerisation at high concentrations in water, thus experimental limitations).
