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:
- November 14 to 22, 2007
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Validation applies, with minor restrictions due to heating rate.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- adopted by the Council on 27th July 1995
- Deviations:
- yes
- Remarks:
- heating rate
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- yes
- Remarks:
- heating rate
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Swiss GLP compliance programme (inspected on November 15 and 16, 2006/ signed on March 29, 2007)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 305 °C
- Atm. press.:
- 97.4 kPa
- Decomposition:
- no
- Remarks on result:
- other: 578 ± 2 K
- Remarks:
- (Normal Boiling point = 305.9°C, estimated with Sydney-Young equation and correction factor extrapolated using values reported in the guideline)
- Conclusions:
- The boiling temperature of test substance has been determined to be 305 ± 2 °C (578 ± 2 K) at 97.4 kPa.
- Executive summary:
The boiling point of the test substance was determined under GLP according to OECD 103/EU A2 guideline, by Siwoloboff (capillary) method.
A sample was heated in a sample boiling capillary tube containing a temperature sensor and a fused capillary containing an air bubble in the lower part, was dipped in the sample tube. A preliminary test was performed with a heating rate of 10 °C/min. After that duplicate measurements were made heating at 2 °C/min.The mean final temperature was retained.
The boiling temperature of test substance has been determined to be 305 ± 2 °C (578 ± 2 K) at 97.4 kPa.
(Normal Boiling point = 305.9°C, estimated with Sydney-Young equation and correction factor extrapolated using values reported in the guideline)
Reference
Preliminary test: 578 K (305 °C) at 97.4 kPa
Determination 1: 578 K (305 °C) at 97.4 kPa
Determination 2: 578 K (305 °C) at 97.4 kPa
Description of key information
The initial boiling point of the test item has been determined to be 305 ± 2 °C (578 ± 2 K) at 97.4 kPa (not corrected to normal atmP)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 305 °C
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available.
Despite minor restrictions, it is considered as a key study. The result is retained as key data for purpose of CSA
