- Executive summary:
The determination of the boiling point of lithium acetate was performed via DSC (differential scanning calorimetry) according to OECD guideline 103. Three events were detected.
The first event was determined at: 106.29 ± 0.98 °C (379.44 ± 0.98 K)
This event did not show the typical form of a glass transition. Therefore it is plausibly assumed that the first event is the dehydration of the test substance, which is also shown by an endothermic event.
The second event (the melting point) was determined at: 284.20 ± 0.13 °C (557.35 ± 0.13 K)
The last event (the beginning decomposition of the test item) was determined at: 379.12 ± 0.34 °C (652.27 ± 0.34 K)
Therefore no boiling point could be determined.
Reference
Pre-Test following SIWOLOBOFF
A colourless condensate was visible at 124 °C. Melting of the test substance was observed at 287 °C. The test item melted to a clear, slightly yellow liquid. At 370 °C many bubbles were visible, but no boiling chain could be observed. A colour change was observed from yellow to brown.
At 374 °C very strong bubble formation was visible and a colourless gas exhausted. The strong reaction of the sample occurred together with a colour change to dirty white. The test was then stopped.
After cooling the test sample solidified as dirty white mass.
Security Pre-Test for the DSC instrument
The weight of the crucible was recorded with 48.27 mg. The crucible remained visually unchanged after heating it to 420 °C in the muffle furnace. The crucible remained visually unchanged after further heating to 600 °C and cooling down. The weight was recorded with 47.03 mg.

Description of key information
No boiling point could be detected as the substance decomposes before boiling.
Key value for chemical safety assessment
Additional information
The boiling point of the lithium acetate was determined according to OECD guideline 103 and EU method A.2. The determination of the boiling point of lithium acetate was performed via DSC (differential scanning calorimetry).
Three events were detected.
The first event was determined at: 106.29 ± 0.98 °C (379.44 ± 0.98 K)
This event did not show the typical form of a glass transition. Therefore it is plausibly assumed that the first event is the dehydration of the test substance, which is also shown by an endothermic event.
The second event (the melting point) was determined at: 284.20 ± 0.13 °C (557.35 ± 0.13 K)
The last event (the beginning decomposition of the test item) was determined at: 379.12 ± 0.34 °C (652.27 ± 0.34 K)
Therefore, no boiling point could be determined.
