PRELIMINARY TEST WITH TGA

From 250°C upwards the weight of the sample decreased significantly. At 354°C, the sample weight had decreased by 25%. After the experiment it was observed that the test substance had evaporated from the sample container.

 

DSC EXPERIMENT

No thermic effects, which could have originated from the melting and/or boiling of the test substance, were observed. After the experiment it was observed that the test substance had evaporated from the sample container.

 

TGA/DSC curves: see attached document.

Applicant's summary and conclusion

Conclusions:
The melting temperature of the substance has been determined to be <-80°C using differential scanning calorimetry and visual observation (GLP-compliant study in accordance with EC A.1, OECD 102 and EPA OPPTS 830.7200).
