- differential scanning calorimetry
- Key result
- Atm. press.:
- ca. 98.8 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 355 - <= 356 °C
- Remarks on result:
- not determinable
- Conclusions:
- Under the conditions of the study, the test material decomposition was observed to begin at 356 °C at 356 °C for test 1 and 355 °C for test 2, this is characterised by an exothermic event.
- Executive summary:
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103 under GLP conditions.
The boiling point of the test material was determined through differential scanning calorimetry. Aliquots of test material (6.73 mg and 7.29 mg) were weighed into 40 µL aluminium crucibles and a lid with a 50 µm diameter orifice cold welded on to them. Each crucible was subjected to the same heating regime, with an air flow of 50 mL/min. The test material is a liquid at room temperature, so the test was started at -60 °C, isothermal for 15 minutes, then heating at 5 °C/min to 20 °C and then 10 °C/min to 400 °C. The sample weights for Test 1 and Test 2 were 6.73 and 7.29 mg respectively. Decomposition was observed to begin at 356 °C for test 1 and 355 °C for test 2, characterised by an exothermic event.
Under the conditions of the study, the test material decomposition was observed to begin at 356 °C.

Additional information
The boiling point of the test material was investigated in accordance with the standardised guideline OECD 103 under GLP conditions. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
