- Key result
- Melting / freezing pt.:
- -32.5 °C
- Atm. press.:
- >= 1 000.1 - <= 1 000.5 mBar
- Decomposition:
- no
- Conclusions:
- The test item has a melting point of -32.5 °C at atmospheric pressure (ca. 1000 mbar) as determined by differential scanning calorimetry according to Regulation (EC) No 440/2008 Method A.1 and OECD Guideline 102.
Reference
At approximately -30 °C, an endothermic effect was detected which can be attributed to the melting of the test item. The onset temperatures are -32.65 °C and -32.26 °C.
No. | Sample weight / g | Onset melting / °C |
PN 317 | 24.91 | -32.65 |
PN322 | 23.25 | -32.26 |
The melting point of the test item is -32.5 °C.
As confirmation a small sample of the test item was stored at -25 °C in the freezer. A visual inspection of the test item showed that the test item was a viscous liquid, but still a liquid at this temperature.
Description of key information
The test item has a melting point of -32.5 °C at atmospheric pressure (ca. 1000 mbar).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -32.5 °C
