Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- July 1995

- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 227 °C
- Atm. press.:
- 100.1 kPa
- Decomposition:
- no
- Conclusions:
- The test substance was determined to boil at 227 °C (500 K) at 100.1 kPa. Essentially identical behaviour was observed on heating the test item in both an air and a nitrogen atmosphere.
- Executive summary:
The boiling temperature of the substance was determined under GLP in accordance with OECD TG 103 (July 1995). The boiling temperature determination was carried out by differential scanning calorimetry (DSC). The temperature accuracy of the DSC was checked prior to testing with indium and zinc. These were within the defined tolerances. Aliquots of the test substance were placed in aluminum crucibles with either pre-perforated or manually pierced lids. The initial temperature was 20 °C and the temperature was increased with a rate of 20 °C/min to 450 °C. Determinations 1-4 were performed under a static air atmosphere, and determinations 5-6 were conducted with a nitrogen atmosphere. The substance behaved essentially similarly under both types of atmosphere. The test substance was determined to boil at 227 °C at 100.1 kPa.

Additional information
Essentially identical behaviour was observed on heating the test item in both an air and a nitrogen atmosphere.
