- Study period:
- from 1999-04-16 to 2000-03-01
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Directive 92/69/EEC
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:

- Specific details on test material used for the study:
- Batch No.: 13111BR
Purity: 99.3 % - Key result
- Boiling pt.:
- 240.8 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 250 °C
- Conclusions:
- The boiling point of the test item was determined to be 240.8 °C.
- Executive summary:
The boiling temperature of the test item was determined according to EPA-Guideline 830.7220 and EEC-Guideline 92/69/EEC A.2. Therefore, a sufficient amount of test substance was filled into glass tubes, which were inserted into the thermosystem at a defined start temperature. The boiling point of the test substance (at 101.3 kPa) was 240.8 °C = 514.0 K
A DSC-Scan, recorded in connection to the determination of the vapour pressure, showed an exothermal decomposition of the test substance beginning at approx. 250 °C. This scan was performed with the test substance in a closed glass pan. Under these conditions the boiling point of the substance was not detectable. Based on these results it can be stated, that the test substance decomposes while boiling.
