Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling pt.:
122 °C
Atm. press.:
15 mm Hg
Remarks on result:
other: Crystalline lactic acid
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).
Executive summary:

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).

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).
