Results and discussion
Melting / freezing point
- Remarks on result:
- other: Test material has been determined to decompose from approximately 518 K at 101.6 +/- 0.1 kPa
Any other information on results incl. tables
Test material decomposed at 518 K. Decomposition was confirmed using a modified liquid bath method. On removal from the apparatus, the test material was confirmed as having decomposed into a black solid.
Applicant's summary and conclusion
- Conclusions:
- The substance was shown to decompose from approximately 518 K at 101.6±0.1 kPa.
- Executive summary:
In a determination of general physico-chemical properties study (Harlan project number: 0959/0234) the test material
is shown to decompose from approximately 518 K (245°C) at 101.6 kPa. The determination was carried out by
differential scanning calorimetry (DSC) using the procedures specified in ASTM E537-86 method and Method A1
melting/freezing temperature of commission regulation (EC) No 440/2008 of 30 May 2008. The methods were
undertaken in two different atmospheres, air (static) and nitrogen to give the same decomposition temperature
indicating the decomposition is probably thermal and not oxidative.
