EC number: 221-800-8
CAS number: 3238-40-2
300°C upwards the weight of the sample decreased significantly. At
361°C, the sample weight had decreased by 25%. After the experiment, a
small amount of charred residue remained in the sample container
(original colour: white to off-white powder). The change of the colour
indicated reaction and/or decomposition of the test substance. It was
also observed that the majority of the test substance was evaporated
from the sample container. TGA-curve: Figure 4 (see attachment).
1: An endothermic peak between 300°C and 400°C was observed. The
extrapolated onset temperature of the peak was 354.75°C. The effect was
most likely obtained due to reaction and/or decomposition of the test
substance. After the experiment, a small amount of charred residue
remained in the sample container. DSC curve: Figure 5 (see attachment).
2: To investigate if the endothermic peak originated from reaction
and/or decomposition of the test substance a lower heating rate of
5°C/minute was applied in this experiment. Figure 6 shows the DSC-curve
obtained. An endothermic peak between 250°C
was observed. The
extrapolated onset temperature of the endothermic peak was 340.65°C. As
can be seen the endothermic peak shifted to lower temperatures. It
demonstrated that reaction and/or decomposition of the test substance
was the reason for the endothermic effect. After the experiment, a small
amount of charred residue remained in the sample container. It was also
observed that the majority of the test substance was evaporated from the
The substance has no melting temperature, it decomposes at > 250°C.
A differential scanning calorimetry (DSC)
test was performed in accordance with EC A.1 and OECD 102.
