- Conclusions:
- The test item melted in a temperature range of 170 - 290 °C under decomposition.
- Executive summary:
The melting point of the test item was tested according to EU Method A.1 and OECD Guideline 102 in a non-GLP study. The test item melted in a temperature range of 170 - 290 °C under decomposition.
Reference
The DSC-measurement of the pre-test in a closed glass crucible with the test item showed an endothermal effect in the temperature range 210 - 225 °C, followed by an exothermic effect in the temperature range 245 °C to 295 °C. At the final temperature of 300 °C a black liquid was observed in the closed glass crucible.
The thermograms show broad multi-stage endothermic signals in the temperature range of about 205 to 350 °C. After the measurements the test item appeared as a black residue. The relative mass loss increased with higher final temperature of the measurement.
Description of key information
The melting point of the test item was tested according to EU Method A.1 and OECD Guideline 102 in a non-GLP study. The test item melted in a temperature range of 170 - 290 °C under decomposition.
Key value for chemical safety assessment
Additional information
No atm. pressure is mentioned in the report, but 1013 hPa as standard conditions can be assumed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
