Two DSC-runs in aluminium crucibles with a hole showed an endothermic effect after melting in the temperature range 310 - 370 °C with an onset temperature of 351 °C. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline.

For the correction of the boiling point to standard atmospheric pressure (1013.3 hPa) the equation, table and graphs of H.B. Hass and R.F. Newton in „CRC Handbook of Chemistry and Physics, 74th ed. 1993-1994", pages 15-16 and 15-17 were used.

Conclusions:
The mean boiling point of the test item at atmospheric pressure (1013.3 hPa) is 351.2 °C.
Executive summary:

The boiling point of the sample was tested according to EU Method A.2 and OECD Guideline 103 in a non-GLP study. The mean boiling point of the test item at atmospheric pressure (1013.3 hPa) is 351.2 °C (of two determinations).
