Preliminary test

From 360°C upwards the weight of the sample decreased significantly. At 426°C the sample weight had decreased by 25%.

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

Main study

A small endothermic effect was observed between 50 and 350 °C. This effect might be due to evaporation of minor compounds but does not derive from melting or boiling of the major compound in E-Y110. Therefore, this effect was not reported as melting or boiling of the test substance. An exothermic effect was observed between 350°C and 400°C. The effect was due to reaction and/or decomposition of the test substance. After the experiment, a black residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test substance.

Applicant's summary and conclusion

Conclusions:
Reaction and/or decomposition of the test substance was observed starting at 350°C (623K). 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.
