- 56.2 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:

- Executive summary:
A test was performed similarly to OECD 102 and Regulation (EC) 440/2008 Method A.1 to determined the melting point of the test item. Three filled capillary tubes were placed in the heating chamber and heated up from 30 °C with a rate of 0.5 K/min. The automatic determination observed a melting of the test article between 54.0 °C and 57.3 °C. After the experiment, the samples were melted and colorless. In conclusion, the melting point of the test item is apparent at 56.2 °C±1.4 °C.
Reference
In order to determine the melting of the test article more precisely, further tests were performed using the capillary tester. A total of nine samples were heated with a heating rate of 0.5 K/min. All samples were completely melted between 54.0 °C and 57.3 °C. During the melting a formation of bubbles could be observed. After the measurement the samples were melted and colorless.
Description of key information
The melting point of the test item is 56.2 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 56.2 °C
