- Executive summary:
The thermal behaviour of test item was assessed unsing the DSC analysis, according to the OECD guideline 102. A small amount of test item was weighed into a one-way 40 μl aluminum crucible and sealed with closed aluminum lid using a capsule presser. Thus prepared capsule was inserted into the furnace of the DSC device and heated from 25 °C to 500 °C with 10 K/minutes heating rate. The measurement was performed under nitrogen atmosphere. Before and after the test, the weight and the appearance of the sample were determined. The test was repeated three times.
During the heating the test item showed endothermic signals in the temperature range of approx. 60 - 170 °C that can be associated with the water evaporation of the test item. Around 300 °C one exothermic peak could be observed, which was assumed to the decomposition of the test item. The endotherm and exotherm peaks in the thermograms do not imply phase transition from a solid to liquid state.
Conclusion
Solid at 20 °C and 1013 hPa.
