- Atm. press.:
- 101.2 kPa
- Decomposition:
- ambiguous
- Conclusions:
- The boiling point of the test item has been determined to be 208 ± 1.0 °C (481 ± 1.0 K) at 101.2 kPa.
- Executive summary:
The boiling point of the test item was determined to be 208 ± 1.0 °C (481 ± 1.0 K) at 101.2 kPa by differential scanning calorimetry, using a procedure 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 to 400 °C, the residues had lost approximately 92% and 100% of their original weight for Determinations 1 and 2, respectively.
Mean boiling point: 208 ± 1.0 °C (481 ± 1.0 K)
Atmospheric pressure: 101.2 kPa
The presence of a light amber stain as the residue on the crucible base after the test was attributed to possible decomposition during boiling.
Description of key information
