Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- 35 °C
Any other information on results incl. tables
In the DSC curve a small glass transition peak was observed at approximately 0 °C in the first experiment. An endothermic peak was observed between 25 and 75 °C. Melting of the test substance probably caused this effect.The extrapolated onset temperature of this peak was determined to be 35 °C. An endothermic effect started at 275 °C. This effect was due to reaction and/or decomposition of the test substance.
The second experiment showed essentially the same results a sduring the first experiment.
Applicant's summary and conclusion
- Conclusions:
- A melting point of 35 °C was observed
- Executive summary:
The melting point of the substance was determined by DSC measurement according to OECD guideline 102.
