Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
not specified

yes
Type of method:
thermal analysis
Remarks:
(DTA, ISTA)
Test material information:
Composition 1
Decomposition:
yes
Decomp. temp.:
100 °C

- There is no melting point and no boiling point up to the decomposition of the test substance

- Pressure is not reported, but atmospheric pressure can be assumed.

Conclusions:
There is no melting point up to the decomposition of the test substance at 100°C (EU method A1).
Executive summary:

The melting point of the substance was tested according to EU method A1. The sample is closed up in a crucible made of glass for each run. First run (DTA): the sample is heated up in steps of 5 K and hold at each temperature for 25 minutes. In comparison with an inert sample (empty crucible) the temperature difference and the heat effect is recorded. Any thermal effect corresponds to a baseline deviation. Exothermal decomposition of Imidoxim starts at 100 °C.

Description of key information

There is no melting point up to the decomposition of the test substance at 100 °C (EU method A1).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
100 °C
