Any other information on results incl. tables

1. Preliminary study

From 275°C upwards the weight of the sample decreased significantly. At 351°C the sample weight had decreased by 25%.

 

After the experiment, a black residue remained in the sample container (original colour: yellow). The change of the colour indicated reaction and/or decomposition of the test substance.

 

2.    Main study

During cooling, a glass transition was observed between -50°C and -20°C (results are archived in the raw data). During heating,aglass transition between -50°C and 0°C was observed. The inflection point of the glass transition was -29.87°C. An endothermic effect was observed between 250°C and 350°C. The effect was due to reaction and/or decomposition of the test substance. After the experiment, a red/brown residue remained in the sample container.

 

Experiment 2 was performed to determine the duplicate melting temperature of the test substance. The temperature program was similar as the program of Experiment 1.Figure6shows the DSC-curve obtained. Similar results as with Experiment 1 were obtained. The inflection point of the glass transition was -29.72°C.After the experiment, a red/brown residue remained in the sample container.

 

The melting temperature (glass transition) was determined as the average melting temperature obtained from Experiment 1 (-29.87°C) and Experiment 2 (-29.72°C).

Applicant's summary and conclusion

Conclusions:

Reaction and/or decomposition of V125226 was observed during DSC experiments at temperatures of > 250°C (> 523K). Boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test substance has no boiling temperature.
