STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: At room temperature
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 225 °C
- Conclusions:
- No melting temperature could be determined. Reaction and/or decomposition of the test item starting at 225°C (498K) was observed.
- Executive summary:
The melting temperature of the test item was determined using differential scanning calorimetry (DSC). Reaction and/or decomposition of the test item was observed during the experiment starting at 225°C (498K). Melting of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the melting temperature of the test item could not be determined.
The study was conducted according to OECD 102 and EC A.1 guidelines and is GLP-compliant and therefore is considered as reliable without restrictions.
Reference
Preliminary test
Starting at 475°C, the weight of the sample decreased significantly. At 497°C, the sample weight had decreased by 25%. After the experiment, a black charred residue remained in the sample container (original colour: white) and a black residue was observed on the lid of the sample container. The change of the colour indicated reaction and/or decomposition of the test item.
Main test
A broad endothermic effect was observed between 100°C and 200°C directly followed by a strong exothermic and small endothermic effect starting at 225°C. The first endothermic effect was most likely obtained due the evaporation of impurities. The exothermic and second endothermic effect was probably obtained due to reaction and/or decomposition of the test item.
After the experiment, a light yellow residue remained in the sample container (original colour: white). The change of the colour indicated reaction and/or decomposition of the test item.
In order to investigate the first endothermic effect, Experiment 2 was stopped directly after the endothermic effect. After the experiment, the residue in the sample container was unchanged (original colour: white). It demonstrated that the endothermic effect was probably obtained by the evaporation of impurities.
Description of key information
The melting temperature of the test item could not be determined. Reaction and/or decomposition of the test item was observed during the experiment starting at 225°C (498K).
Key value for chemical safety assessment
Additional information
The study to determine the melting temperature of the test item was conducted according to OECD 102 and EC A.1 guidelines using differential scanning calorimetry (DSC) (Volic 2019).
The study was conducted according to standard guidelines and is GLP-compliant and therefore is considered as reliable without restrictions (Klimisch 1).
