Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- As the test material was a thick, viscous liquid, it was not possible to determine the boiling point using a conventional method.
The test material (approximately a 2 cm layer) was placed in a beaker and heated on a hotplate. The temperature was recorded using a thermometer. - GLP compliance:
- yes
- Type of method:
- other: Non-standard method
- Key result
- Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 210 °C
- Conclusions:
- The test material was found to decompose from 210 °C (483 K) without boiling.
- Executive summary:
As the test material was a thick, viscous liquid, it was not possible to determine the boiling point using a conventional method. The test material (approximately a 2 cm layer) was placed in a beaker and heated on a hotplate. The temperature was recorded using a thermometer.
As the test substance was heated to 160 to 165 °C, small bublles formed and it was observed that the colour of the test substance had lightened. At 190 °C, a white vapour appeared which became a constant stream by 210 °C. The boiling point is therefore reported as the decomposition temperature of 210 °C.
The test material was found to decompose from 210 °C (483 K) without boiling.
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14th January 1993 to 18th May 1994
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- > 149 °C
- Atm. press.:
- ca. 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 320 °C
- Conclusions:
- Two endothermic peaks were observed, at 231 and 342 °C. Samples were examined by fourier transform IR spectroscopy after heating. Material retrieved at 220 °C appeared to be unchanged from the starting material. It was therefore assumed that the first transition was boiling (with an onset temperature of 149 °C). Material retrieved at 320 °C indicated that decomposition had occurred.
- Executive summary:
The boiling point of the test material was determined by differential scanning calorimetry (DSC). Two main endothermic transitions were observed in the DSC curve. Two peaks were observed at 231 °C and 342 °C. respectively. Two separate runs were therefore performed with the DSC pans removed from the calorimeter for analysis by
fourier transform infra-red spectroscopy (FTIR) at 220 °C and 320 °C, respectively.
Samples were examined by FTIR spectroscopy after heating. Material retrieved at 220 °C appeared to be unchanged from the starting material. It was therefore assumed that the first transition was boiling (with an onset temperature of 149 °C). Material retrieved at 320 °C indicated that decomposition had occurred.

Description of key information
The test material was found to decompose before boiling.
