Appearance of the Samples

Before the test the appearance of the test item was light yellow, viscous liquid. After the experiments the test item was unchanged in the crucible.

Results

Using a linear heating / cooling rate of 2 °C/min the freezing point of the test item was determined to be -25 °C (248 K).

Conclusions:
The freezing point of the test item was determined with DSC to be -25 °C.
Executive summary:

A study was conducted according to OECD TG 102, Regulation (EC) No 440/2008 method A.1 and EPA OPPTS 830.7200 to determine the freezing point of the test item using differential scanning calorimetry. The test item was weighed into an aluminium crucible under an inert atmosphere (nitrogen). Three tests 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 -30 °C and heated again to room temperature with a constant heating rate of 2 °C/min. The freezing point of the test item was determined to be -25 °C at atmospheric pressure (1013 hPa).

Description of key information

The freezing point of the test item was determined to be -25 °C.
