Results and discussion
Any other information on results incl. tables
No melting point of the Test Item was observed within the instrument and calibration threshold of 410 °C.
Using the preliminary temperature gradient of 25°C to 41ºC at a rate of 10°C/min to determinate the approximate melting point, the average result was 318.8°C and it was observed that the colour of the Test Item changed to dark brown which indicated decomposition. No other changes were observed up to 410 °C. The Test Item was then analysed using a temperature gradient of 290°C to 330°C at a rate of 0.5°C/min to accurate determinate the melting point. The Test Item started to show brown speckles within the white solid powder at approximately 290°C which indicated decomposition. At 295.9°C the Test Item has turned into a black liquid.
Applicant's summary and conclusion
- Conclusions:
- The melting point of the test material was not determined. The test material decomposed at 290ºC.
- Executive summary:
Introduction
The study was undertaken to determine the melting point of the test material. The method used was designed to be compatible with OECD Guideline 102.
Results & Conclusions
The melting point of the test material was not determined. The test material decomposed at 290ºC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
