- Executive summary:
The melting temperature of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 102, EU Method A.1 and EPA OPPTS 830.7200, and under GLP conditions.
During the study, the melting and boiling temperature of the test material were tested by DSC.
Under the conditions of the study, the melting temperature of the test material was determined to be < -83.6 °C (189.6 K) at 1013.25 hPa applying a storage experiment in the freezer.
Reference
Preliminary Test
Starting at 225 °C, the weight of the sample decreased significantly. At 247 °C, the sample weight had decreased by 25 %.
After the experiment, a black charred residue remained in the sample container (original colour: colourless). The change of the colour indicated reaction and/or decomposition of the test material.
Main Study
The DSC curve obtained is attached.
During cooling, no effects were observed. During heating an endothermic effect was observed starting at 175 °C. The endothermic effect was probably obtained due to reaction and/or decomposition of the test material.
After the experiment, a black molten residue remained in the sample container (original colour: colourless). The change of the colour indicated reaction and/or decomposition of the test material.
After the additional investigation of the melting temperature of the test material was performed (placing two sub-samples of the test material for 94 hours at -20.3 ± 2 °C and at -83.6 ± 1.7 °C respectively) it was observed after storage that the test material was a liquid (-20.3 ± 2 °C) and a very viscous liquid (-83.6 ± 1.7 °C). According to this it was concluded that the melting temperature of the test material is < -83.6 °C (<189.6 K).
Description of key information
Under the conditions of the study, the melting temperature of the test material was determined to be < -83.6 °C (189.6 K) at 1013.25 hPa applying a storage experiment in the freezer.
Key value for chemical safety assessment
Additional information
The melting temperature of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 102, EU Method A.1 and EPA OPPTS 830.7200, and under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
During the study, the melting and boiling temperature of the test material were tested by DSC.
Under the conditions of the study, the melting temperature of the test material was determined to be < -83.6 °C (189.6 K) at 1013.25 hPa applying a storage experiment in the freezer.
