other: No boiling temperature observed

- Preliminary Test: Starting at 225°C, the weight of the sample decreased significantly. At 298°C, the sample weight had decreased by 25%. After the experiment no residue was observed in the sample container.

- Main Study: During cooling, no effects were observed which were due to crystallization of the test material. During heating, an exothermic signal was observed between 300 and 350°C. After the experiment, however, it was observed that the sample container had fallen of its platform. This event might have caused the exothermic signal and it was decided not to consider it during data interpretation. A yellow/brown residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test material.

- Experiment 2: Less test material was used. An endothermic peak was observed between 275 and 375°C. The endothermic effect was due to reaction and/or decomposition of the test material. After the experiment, a yellow/brown residue remained in the sample container (original colour: colourless). The change of the colour confirmed reaction and/or decomposition of the test material.

- Reaction and/or decomposition of the test material was observed during DSC experiments at temperatures of > 275°C (> 548 K). Boiling of the test material was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test material has no boiling temperature.

Conclusions:

Under the conditions of this study, reaction and/or decomposition of the test material was observed at temperatures of > 275°C (> 548 K). Boiling of the test material was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test material has no boiling temperature.

Executive summary:

The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2. and OPPTS 830.7220 under GLP conditions using Differential Scanning Calorimetry. Under the conditions of this study reaction and/or decomposition of the test material was observed at temperatures of > 275°C (> 548 K). Boiling of the test material was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test material has no boiling temperature.

Additional information

Key Study, Reingruber (2017)

The boiling point of the test material was investigated in accordance with the standardised guidelines OECD 103, EU Method A.2. and OPPTS 830.7220 under GLP conditions using differential scanning calorimetry. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997). Under the conditions of this study reaction and/or decomposition of the test material was observed at temperatures of > 275°C (> 548 K). Boiling of the test material was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test material has no boiling temperature.
