Key result

Melting / freezing pt.:

< -100 °C

Atm. press.:

1 005.2 hPa

Decomposition:

no

Sublimation:

no

During the cooling phase, no thermal effects were observed in the temperature range of -100 to 25 °C. 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 -100 °C.

Conclusions:

The test item has no melting point down to a temperature of -100 °C at atmospheric pressure (1005 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).

Executive summary:

Melting point of the test item was determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995). The test item was weighed out into an aluminium crucible under an inert atmosphere. Two tests with about 9 – 11 mg of the test item were performed. After check-weighing, the perforated lid was attached using a crucible press. As reference crucible, an empty aluminium crucible was used.

At ambient conditions, the test item is a liquid. 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. During the cooling phase, no thermal effects were observed in the temperature range of -100 to 25 °C. Thus, 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 -100 °C.
