- Key result
- Melting / freezing pt.:
- < -40 °C
- Atm. press.:
- 1 atm
- Conclusions:
- The test item has a melting point below -40 °C.
- Executive summary:
The melting point of the test item was investigated by DSC measurements. The test item has a melting point below -40 °C.
Reference
Test item runs:
The Melting Point DSC runs were carried out, in duplicate, on approx. 4 to 5 mg portions of the test item, in 50 µL aluminium crucibles. The crucibles were sealed with crimped lids. The samples were cooled to - 50 °C and then heated to +30 °C at 10 °C per minute in a test chamber of nitrogen at a purge rate of approximately 20 mL/minutes.
The following results were obtained:
a) < - 40 °C
b) < - 40 °C
average: < - 40 °C
Neither test run showed a melting endotherm at a temperature greater than - 40 °C (i.e. under the conditions of this test, the test item does not freeze).
As a further check a portion of the test item, in a small vial, was placed in a freezer at a temperature of - 30 °C. It was noted that the sample became viscous but did not freeze at this temperature.
Description of key information
The test item has a melting point below -40 °C.
Key value for chemical safety assessment
