Composition 1
Reference:
Composition 0
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Principles of method if other than guideline:
The melting temperature was measured by Differential Scanning
Calorimetry in accordance with DIN 51005.
GLP compliance:
yes (incl. certificate)
Type of method:
thermal analysis
Test material information:
Composition 1
Melting / freezing pt.:
< -100 °C

No melting temperature was found between -100°C and vaporization/decomposition of the test item.

An endetherrnie peak, starting at about 200°C (onset), with a loss of mass of about 1 00% at the end of the run, can be attributed

to the vaporization / decomposition of the test item.

To survey the thermic behaviour of the test item the determination was run up to 400°C.

After this run the DSC-crucible was empty.
