Materials and methods

Principles of method if other than guideline:

Thermogravimetric Analysis (TGA) was used to determine thermal characteristics of the test material. Via TGA, thermal decomposition and relative weight percent values were observed. Differential Scanning Calorimetry (DSC) was also explored to verify that the sample is degrading, rather than boiling.

GLP compliance:

no

Any other information on results incl. tables

An exothermic peak was observed during DSC with the test material.

Via TGA, using a maximum temperature ramp of 10 °C per minute with a resolution setting of 3 in an atmosphere of nitrogen, the onset of weight loss occurs at 215 °C.

The single weight loss event for this material occurs at derivative peak of 232°C, resulting in 100 % weight loss.

Via DSC, an exotherm was observed rather than an endotherm, indicating sample degradation (not boiling) is the dominant factor in the volatilization seen in the TGA curve.

The onset of the exotherm occurs at 189 °C when heated at a rate of 5°C per minute

Applicant's summary and conclusion

Conclusions:

Under the conditions of the test, the test material was found to decompose before boiling. The onset of decomposition commenced at 189 °C.

Executive summary:

The boiling point of the test material was evaluated using thermogravimetric analysis and differential scanning calorimetry. TGA was used to determine thermal characteristics of the test material. Via TGA, thermal decomposition and relative weight percent values were observed. DSC was also explored to verify that the sample is degrading, rather than boiling. Under the conditions of the test, the test material was found to decompose before boiling. The onset of decomposition commenced at 189 °C.
