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:
- 5 June 1997 - 21 August 1997
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Atm. press.:
- 762 mm Hg
- Decomposition:
- yes
- Decomp. temp.:
- > 270 °C
- Conclusions:
- The boiling point of DPGDB is not determinable as the test material decomposes above 270ºC (543K).
- Executive summary:
A package of testing, including a determination of the boiling point was conducted to determine the physico-chemical properties of the test material DPGDB. The determination of boiling point was conducted according to OECD and EC test guidelines, and in compliance with GLP.
The boiling point of DPGDB was not determinable as the test material decomposed above 270°C (543K) with no sign of boiling.
Reference
In duplicate determinations at 762 mmHg, DPGDB was found to darken at temperatures above 270°C with no sign of boiling, indicating decomposition.
Description of key information
The boiling point of DPGDB was not determinable as the test material decomposed above 270°C (543K) with no sign of boiling (HLS 1999, VCL249/972399).
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 270 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
