- 320 °C
- Atm. press.:
- 99.5 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 320 °C
- Conclusions:

- Executive summary:
Boiling Point. Boiled with decomposition from approximately 320 °C (593 K) at 99.5 kPa by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

After heating, the samples had lost approximately 93% and 92% of their original weight for Determinations 1 and 2 respectively.
Result: boil with decomposition from approximately 320 °C (593 K).
Discussion:
Due to the low enthalpy change at the onset of decomposition the temperature can only be approximated. The onset has been reported as from the lower of the observed onsets.
