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:
- 29 July 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: capillary method
- Boiling pt.:
- 334.85 °C
- Remarks on result:
- other: no information on atm pressure provided
- Conclusions:
- Under the conditions of the test, the boiling point of the test material was determined to be 334.85 °C (608 K), using the capillary method.
- Executive summary:
The boiling point of the test material was determined using the capillary method under GLP conditions and in accordance with the standardised guidelines OECD 103 and EU Method A.2.
Based on the findings of the submitted melting point study, 201.9 °C was considered to be the starting temperature of this experiment. A small amount of the test material was heated in the electronic controlled sample block and the temperature around the sample was displayed. The test material was assessed visually for any possible changes in its appearance, consistency and colour.
During the preliminary test, the sample was heated in the range of 200 - 400 °C with 10 °C/min heating rate. The boiling point was observed approximately around 335 °C.
According to the preliminary test boiling point was observed, therefore the samples in a glass tube were heated from 325 °C to 340 °C with a rate of 0.5 °C/min. The colour of the test material was brown and black by the increase of temperature. The first bubbles were observed around 325.1 °C. The test material was bubbling from around 328.2 °C, and the boiling point is 334.85 °C.
Under the conditions of the study, the boiling point was determined to be 334.85 °C, equivalent to 608 K.
