- Executive summary:
Boiling Point. Decomposed from approximately 200°C (473 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.
Reference
The thermographic data for Determinations 1 and 2 are shown in the following table:
| Approximate Temperature (°C) | |||
| Thermal Event | Interpretation | Determination 1 | Determination 2 |
| exotherm | decomposition | 200 | 200 |
Atmospheric pressure : 101.4 kPa
After heating, the samples had lost approximately 42% and 46% of their original weight for Determinations 1 and 2 respectively.
Result: decomposition from approximately 200 °C (473 K).
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 start of the rise in the baseline of the thermograms.
