Overall result: Boiling with decomposition from 632 K
Discussion:
On examination of the crucible after testing, the presence of a brown stain around the periphery of the crucible indicated decomposition of the test material. Similar thermographic profiles were obtained using air and nitrogen atmospheres; this indicates that the observed decomposition in both determinations is probably thermal and not oxidative.
Description of key information
The boiling point of the substance was determined as 359 °C (632 K) at 102.44 kPa according to OECD Guideline 103 by Differential Scanning Calorimetry (DSC). During boiling the substance was found to decompose thermally.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 632 K
Additional information
The substance was found to decompose thermally during boiling. The boiling point (with decomposition) was determined as 359 °C (632 K) at 102.44 kPa.
