Remarks:
No melting point and no boiling point could be detected between -150 °C up to 450 °C. Decomposition started at approx. 175 °C

No boiling point could be determined between -150 °C and 450 °C. Decomposition started at approx. 175 °C.

Conclusions:
The boiling point of the test item was determined according to EU Method A.2 (Boiling Temperature). No melting point and no boiling point could be detected between -150 °C up to 450 °C. Decomposition of the substance started at approx. 175 °C. The substance is solid at ambient temperature.
Executive summary:

Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC): The sample is closed up in a crucible made of aluminium with perforated lid and cooled down in a DTA/DSC-system to -150 °C. Then the sample was heated up to 450 °C (heating rate 5 K/min). In comparison with an inert sample (empty crucible) the temperature difference and the heat effect are recorded.

No boiling point could be determined between -150 °C and 450 °C. Decomposition of the substance started at approx. 175 °C. But the substance is solid at ambient temperature.

This procedure conforms to test method A.2 (section 1.4.6), „determination of the boiling point“, described in the EC-Guideline.

Description of key information

The boiling point of the test item was determined according to EU Method A.2

(Boiling Temperature). No boiling point could be detected between -150 °C up to 450 °C.

Key value for chemical safety assessment

Additional information

At ambient temperature the test item is solid but no melting point and no boiling point could be detected until the decomposition of the substance starting at approx. 175 °C.
