- Executive summary:
Boiling Point. Decomposed from approximately 240 °C (513 K) at 101.4 kPa by differential scanning calorimetry, 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.

After heating, the samples had lost approximately 26% and 38% of their original weight for Determinations 1 and 2 respectively.
Result: decomposition from approximately 240 °C (513 K).
Discussion:
Due to the low enthalpy change at the onset of decomposition the temperature can only be approximated. The decomposition temperature has been reported as approximately that of the first rise in the baseline.
