- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 05.03.2018 to 07.03.2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 236.8 °C
- Conclusions:
- The substance started to decompose at 236.8 °C (510.0 K).
- Executive summary:
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 and EPA OCSPP test guideline 830.7200 to determine the melting point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). A small amount of test item was weighed into a one-way 40 µL aluminum crucible. As reference crucible, an empty aluminium crucible was used. The prepared capsule was inserted into the furnace of the DSC device and heated from room temperature to 500 °C with 10 °C/min heating rate. The measurements were performed under nitrogen atmosphere. The experiment was performed in triplicate. Based on the thermograms and the appearance of test item after the tests, it was concluded the test item started to decompose at 236.8 °C (510.0 K).
Reference
Before the test the appearance of the test item was a white powder. After the experiments the test item became a black powder in the crucible.
