During the cooling and the subsequent heating phase, no thermal effects were observed in the temperature range from -90 to ambient temperature. It can be assumed that the test item has no melting or freezing point in this temperature range. Therefore the test item has no melting point down to a temperature of -90 °C.
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 11 -12 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 and the subsequent heating phase, no thermal effects were observed in the temperature range from -90 to ambient temperature. Therefore it was concluded that the test item has no melting point down to a temperature of -90 °C.
The melting point was determined to be below -90 °C at 1013.25 hPa.
