- Boiling pt.:
- >= 355 - <= 420 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:

- Executive summary:
A study was conducted according to OECD TG 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item and the reference were weighed into an aluminium crucible under an inert atmosphere (nitrogen). The crucibles were heated from room temperature up to 500 °C at a constant heating rate. Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 355 - 420 °C. At approximately 430 °C an exothermal effect started (only first measurement, the second was terminated beforehand). The mass loss after the DSC measurements amounted to 86 % (second measurement).
The discolouration at 248.6 °C indicated decomposition before boiling took place. Hence, the test item boiled under decomposition within a range of 355 - 420 °C under atmospheric conditions.
Reference
Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 355 - 420 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline. At approximately 430 °C an exothermal effect started (only first measurement, the second was terminated beforehand). The mass loss after the DSC measurements amounted to 86 % (second measurement).
