Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- see 'principles of method if other than guideline'
- Principles of method if other than guideline:
- The sample was heated in tubes and a capillary inserted into the tube. The instrument applied a programmed temperature gradient across the expected temperature range and the boiling point was determined by visual inspection. Boiling point was reached when a steady and continuous flow of bubbles was released from the plunged end of the capillary.
- GLP compliance:
- no
- Remarks:
- Conducted in a GLP compliant laboratory but not as part of a formal GLP study
- Type of method:
- other: visual assessment method - comparable to the method according to Siwoloboff and the photocell method
- Boiling pt.:
- > 400 °C
- Atm. press.:
- 102.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- > 400 °C
- Remarks on result:
- other: Colour darkened and a few bubbles appeared above 370°C, suggesting possible degradation.
- Conclusions:
- Possible degradation was observed at 350°C and 370°C. The instrument reached its maximum operating temperature at 400°C, therefore no further analysis could be performed above this temperature. The boiling point was therefore reported as >400°C.
- Executive summary:
The boiling point of the test substance was determined in accordance with the EU Testing Method A.2. The boiling point was determined using a Buchi B545 Melting Point Instrument in accordance with EU Method A.2. Although the use of the visual assessment method is not explicitly stated in the EU A.2. test guideline, the method used is comparable to the principle of the method according to Siwoloboff and the photocell method. Possible degradation was observed at 350°C and 370°C. The instrument reached its maximum operating temperature at 400°C, therefore no further analysis could be performed above this temperature. The boiling point was therefore reported as >400°C.
Reference
Preliminary assessment of the boiling point was performed, in duplicate, at a temperature gradient of 100°C to 400°C at a rate of 5°C/min. This gave an observed change of colour at 350°C (yellow) and 370°C (dark golden brown), suggesting possible degradation. The sample was not observed to boil in this range, but a few bubbles were observed from 370°C onward. No further analysis was performed as the instrument had reached the upper temperature limit of 400°C.
Description of key information
A study was conducted on the registered substance to determine the boiling point of the substance. The boiling point of the test substance was determined in accordance with the EU Testing Method A.2. The boiling point was determined using a Buchi B545 Melting Point Instrument in accordance with EU Method A.2. Although the use of the visual assessment method is not explicitly stated in the EU A.2. test guideline, the method used is comparable to the principle of the method according to Siwoloboff and the photocell method. Possible degradation was observed at 350°C and 370°C. The instrument reached its maximum operating temperature at 400°C, therefore no further analysis could be performed above this temperature. The boiling point was therefore reported as >400°C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 400 °C
