Executive summary:

GUIDELINE

The determination was carried out by differential scanning calorimetry using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

RESULTS

The boiling temperature of the test item was determined to be from approximately 281 °C (554 K) at 102 kPa. The test item had a broad boiling range with an extrapolated onset of approximately 400 °C (673 K).
