Two DSC-runs in aluminium crucible with a hole showed an endothermic effect (melting) in the temperature range 260 - 280 °C with an onset temperature of 263 - 264 °C. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with baseline. No other effect was observed up to 450 °C.

Ident-No.

The endothermic effect in the temperature range 260 - 280 °C was assigned to the melting point. As no other effect was observed the test item has no boiling point up to 450 °C.

Conclusions:
No boiling was observed in the temperature range 25 - 450 °C.
Executive summary:

The boiling point of the test item was determined according to OECD test guideline 103 and Regulation EC No. 440/2008, Method A.2. Differential scanning calorimetry (DSC) measurements were performed. The test item was heated up from ambient to 450 °C. No boiling was observed up to this temperature.

Description of key information

No boiling was observed in the temperature range 25 - 450 °C (reference 4.3-1).

Key value for chemical safety assessment
