- ca. 375 °C
- Remarks on result:
- not determinable
- Remarks:
- Boiling point of the test item was not observed below the temperature at which the test item decomposes

Reference
8.4.1. Preliminary Test
The TGA curve of the test item is shown in Figure 1 (attached). Starting at 50°C, the weight of the
sample decreased significantly.
After the experiment, a dark grey residue remained in the sample container (original colour:
colourless). The change of the colour indicated reaction and/or decomposition of the test
item.
8.4.2. Main Study
The DSC curve obtained with Experiment 1 is shown in Figure 2 (attached). An endothermic peak was observed between 0°C
and 175°C. The endothermic effect was most likely obtained due to evaporation of volatile
components and reaction and/or decomposition of the test item. An endothermic peak was
observed starting at 375°C. The endothermic effect was due to reaction and/or
decomposition of the test item.
After the experiment, a colourless solid residue remained in the sample container.
Experiment 2 was performed as a duplicate of the glass transition temperature. Figure 3 (attached)
shows the DSC curve obtained.
Description of key information
Reaction and/or decomposition of the test item was observed. Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
