- yes
- Decomp. temp.:
- ca. 200 °C
- Remarks on result:
- other: Reaction and/or decomposition of the test substance was observed starting at 200°C (473K).
Any other information on results incl. tables
An endothermic peak starting at 275°C was observed. The effect was most likely obtained due to reaction/decomposition of the test substance. After the experiment, a yellowish molten residue remained in the sample container. To investigate the reaction/decompositionstarting at 275°C,a higher end temperature was applied in the second experiment. Between 200°C and 270°C, an endothermic peak was observed. The effect was most likely obtained due to reaction/decomposition of the test substance.
An exothermic peak was observed between 270°C and 350°C. The effect was most likely obtained due to further reaction/decomposition of the test substance. A second endothermic peak was observed between 350°C and 400°C, this effect was most likely due to evaporation of the residue. To investigate the reaction/decomposition peak between 200°C and 270°C, a lower heating rate of 10°C/minute was applied in the third experiment. Under these conditions, the endothermic peak shifted to lower temperatures. It demonstrated that reaction and/or decomposition of the test substance was the reason for the endothermic effect. After the experiment, a yellow/orange molten residue remained in the sample container.
Applicant's summary and conclusion
- Conclusions:
- The test substance has no boiling temperature, reaction and/or decomposition of the test substance was observed starting at 200°C (473K).
