Results and discussion
Melting / freezing point
- Atm. press.:
- 101.8 kPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 603 K
Any other information on results incl. tables
The DSC study was conduted in two determinations, air (static) and nitrogen where the test material decomposed at 603 K under both conditions.
Applicant's summary and conclusion
- Conclusions:
- The test material was shown to decompose from approximately 603 K.
- Executive summary:
In a determination of general physico-chemical properties study (Harlan project number: 0959/0224) the test material is shown to decompose from approximately 603 K (330°C) at 101.8 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
