- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 and EPA OCSPP test guideline 830.7200 to determine the melting point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 18 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. The substance is a liquid at ambient conditions. Therefore the crucibles were cooled down from ambient temperature to -100 °C with a constant cooling rate of 0.25 K/min under an inert atmosphere. After a waiting period of 30 min at -100 °C, the temperature was increased up to 500 °C at a constant heating rate of 10 K/min. During the cooling phase, no thermal effects were observed, which can be associated with the freezing of the test item. During the heating phase a small endothermic effect could be observed in the temperature range of approximately -80 to -60 °C, which cannot be assigned to the melting of the test item, due to the low energy of this effect. Therefore, the test item has no melting point down to -100 °C under atmospheric pressure. No observations were made which cause doubt on the validity of the outcome of the study.
Reference
During the cooling phase, no thermal effects were observed, which can be associated with the freezing of the test item. During the heating phase a small endothermic effect could be observed in the temperature range of approximately -80 to -60 °C, which cannot be assigned to the melting of the test item, due to the low energy of this effect. Therefore, the test item has no melting point down to -100 °C under atmospheric pressure. At room temperature, the test item is a liquid. The test item showed a second endothermic signal in the temperature range of 220 – 340 °C that can be associated with the boiling of the test item.
Description of key information
The test item has no melting point down to a temperature of -100 °C at 1013.25 hPa.
Key value for chemical safety assessment
