EC number: 203-016-8
CAS number: 102-24-9
8.4.1. Preliminary Test
The TGA curve of the test item is shown in Figure 1 (attached).
Starting at 50°C, the weight of the
sample decreased significantly.
After the experiment, a dark grey residue remained in the sample
container (original colour:
colourless). The change of the colour indicated reaction and/or
decomposition of the test
8.4.2. Main Study
The DSC curve obtained with Experiment 1 is shown in Figure 2
(attached). An endothermic peak was observed between 0°C
and 175°C. The endothermic effect was most likely obtained due to
evaporation of volatile
components and reaction and/or decomposition of the test item. An
endothermic peak was
observed starting at 375°C. The endothermic effect was due to reaction
decomposition of the test item.
After the experiment, a colourless solid residue remained in the sample
Experiment 2 was performed as a duplicate of the glass transition
temperature. Figure 3 (attached)
shows the DSC curve obtained.
Reaction and/or decomposition of the test item was
observed. Boiling of the test item was not observed below the
temperature at which reaction and/or decomposition started. Based on
this, the test item has no boiling temperature.
