- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 269.9 °C
- Conclusions:

- Executive summary:
Findings and Results:
First, a small amount was heated in a test tube in the aluminium block in the pre-test. Decomposition was observed, indicated by colour change and physical state change (the test item charred).
The determination of the main test of the boiling point following theSiwoloboffmethod was performed in duplicate. In both determinations, decomposition was detected.
The decomposition temperature was determined with 269.9 ± 0.0 °C (543.1 ± 0.0 K). This value is the means of two independent determinations.
The test item showed signs of decomposition while melting, indicated by colour change. Therefore, no boiling point could be determined.
Reference
A small amount of the test item was filled into a small test tube and was heated in an aluminium block from room temperature with a gas burner.
The following observations were observed:

After cooling down: The test item was hard and charred. The determination of boiling point could not be determined. The test item decomposed while melting.
Description of key information
The test item EDA-DOPO showed a decomposition while melting, no boiling point could be determined. Decomposition was indicated by colour change and in the pre-test, the test item also charred.
Key value for chemical safety assessment
Additional information
The test item EDA-DOPO showed a decomposition while melting, no boiling point could be determined. Decomposition was indicated by colour change and in the pre-test, the test item also charred.
