- Batch No.of test material: 147-270300-1 - Key result
- Decomposition:
- yes
- Decomp. temp.:
- 85 °C

- Executive summary:
A study was conducted according to Regulation (EC) No 92/69 method A.2 and OECD test guideline 103, to determine the boiling point of the test item using differential thermal analysis (DTA). The test item was weighed out in an aluminium crucible. The substance was heated at a constant heating rate of 5 K/min. At 85 °C decomposition began and till this temperature no boiling was observed. No observations were made which cause doubt on the validity of the outcome of the study.
Reference
The sample was closed up in a crucible made of aluminium with perforated lid and heated up in a DTA-system with a heating rate of 5 K/min. The boiling curve of the sample was a steep endothermic signal.
Description of key information
The test item decomposes at 85 °C. Thus, no boiling point can be defined.
Key value for chemical safety assessment
