- Guideline:
- other: REACH guidance on QSAR R.6
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- OECD Guideline No. 103 for the testing of chemicals, 27 July 1995.
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Regulation (EC) No 440/2008, Method A.2
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Boiling pt.:
- 412.13 °C
- Atm. press.:
- 760 mm Hg
- Remarks on result:
- other: calculated using MPBPWIN v1.43
- Key result
- Atm. press.:
- 99.4 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 230 °C
- Conclusions:
- The boiling point of the test item could not be determined, due to decomposition. The decomposition of the test item started at 230 °C. Therefore, the boiling point was calculated using MPBPWIN v1.43. The boiling point was calculated as 412.13 °C.
- Executive summary:
A study was conducted to determine the boiling point of the test item. The study was performed according to Regulation (EC) No 440/2008 method A.2 and OECD Guideline No. 103 for the testing of chemicals, 27 July 1995. Therefore, the method of Siwoloboff was used. The test substance was heated in a sample tube, which was placed in a heating block. The test started at 220 °C. The colour of the test substance changed from white to light brown at about 230 °C and to dark brown at about 250 °C. Due to decomposition of the test item, no boiling point could be determined.
Additional the boiling point of the test item was estimated by an Atom/Fragment Contribution Method. The boiling point of the test substance was estimated to 412.13 °C by the adapted Stein and Brown method.
Reference
The atmospheric pressure during the test was 99.4 kPa (calibrated barometer GPB 2300, Petrotest, Germany).
The test started at 220 °C. The colour of the test substance changed from white to light brown at about 230 °C and to dark brown at about 250 °C.
At about 250 °C the decomposed test substance started boiling and bubbles emerged rapidly from the lower open end of the capillary. Between 260 °C and 330 °C the test substance boiled but the capillary was no longer observable. At about 330 °C the test substance boiled over.
Identical observations were made in both samples.
Therefore no boiling temperature of the test substance could be determined. The test item decomposed before boiling. Decomposition was indicated by a significant change of colour at about 230 °C.
Additional the boiling point of the test item was estimated by an Atom/Fragment Contribution Method. The boiling point of the test substance was estimated to 412.13 °C by the adapted Stein and Brown method.
Description of key information
The boiling point of the test item could not be determined, due to decomposition. The decomposition of the test item started at 230 °C. Therefore, the boiling point was calculated using MPBPWIN v1.43. The boiling point was calculated as 412.13 °C (referenc 4.3-1).
Key value for chemical safety assessment
