TGA EXPERIMENT (PRELIMINARY TEST)

Significant decrease of weight from 125°C. 25% weight loss at 368°C and 70% weight loss at 420°C.

After the experiment, a dark brown residue remained in the sample container. The change of the colour indicated reaction and/or decomposition of the test item.

 

DSC EXPERIMENT 1

During cooling a glass transition was observed between-60°C and -80°C. 

During heating a glass transition was observed between -75°C and -50°C (inflection point: -65.447°C) and a second glass transition was observed between -50°C and 0°C (inflection point: -16.154°C).

From 100°C an exothermic effect was observed. After the experiment, a dark brown molten residue remained in the sample container (original colour: amber). The exothermic effect was most probably obtained due to reaction and/or decomposition of the test item.

DSC EXPERIMENT 2

Similar results as in Experiment 1 were obtained. Inflection points of the glass transitions: -66.472°C and -17.639°C. 

DSC EXPERIMENT 3

The difference in the inflection point between Experiment 1 and Experiment 2 was > 0.5°C. Therefore Experiment 3 was performed using the same temperature program. 

First inflection point: -64.155°C; second inflection point: -16.039°C. After the experiment, a dark brown molten residue remained in the sample container. 

DATA HANDLING

The first glass transition point obtained from Experiment 1 (-65.447°C), Experiment 2 (-66.472°C) and Experiment 3 (-64.155°C) and the second glass transition point obtained from Experiment 1 (-16.154°C), Experiment 2 (-17.639°C) and Experiment 3 (-16.039°C) are reported as a range, as the inflection points differed significantly.

Applicant's summary and conclusion

Conclusions:

A glass transition range between -64.2°C and -66.5°C and a second glass transition range between -16.0°C and -17.6°C were determined.
The substance has no melting/freezing temperature between 25°C and -90°C.

Executive summary:

Differential Scanning Calorimetry (DSC) experiments were performed in a GLP study according to EC A.1, OECD 102 and OPPTS 830.7200.

The liquid substance has no melting/freezing temperature between 25°C and -90°C. From triplicate measurements, a glass transition range between -64.2°C and -66.5°C and a second glass transition range between -16.0°C and -17.6°C were determined.

During heating from -90°C to 368°C reaction and/or decomposition of the substance started at 100°C.
