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:
- From November 2001 to January 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- not specified
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- Lot no: MRT-2518-038
Identity: C12-14 ADEBAC
Purity: 68 % C12-alkyl compound, 32 % C14-alkyl compound
Appearance: White solid
Storage: Room temperature, desiccated - Key result
- Atm. press.:
- 1 008 mBar
- Decomposition:
- yes
- Decomp. temp.:
- > 140 °C
- Remarks on result:
- not determinable
- Remarks:
- The test substance decomposed at temperatures above 140ºC without boiling.
- Conclusions:
- Under study conditions, boiling point of the test substance was not determinable, as the test substance decomposed at temperatures above 140ºC without boiling (Sydney 2002).
- Executive summary:
A study was conducted to determine the boiling point of test substance, C12-14 ADEBAC (active not specified), using modified Siwoloboff method according to the OECD Guideline 103 and EU Method A.3, in compliance with GLP. During the experiment, the test substance was observed to become clear and less viscous before darkening commenced at approximately 140ºC. Heating was continued at 10ºC /minute from 150ºC to 220ºC, and 1ºC/minute thereafter, until the decomposed samples, now light brown in color, boiled at approximately 230ºC. Under study conditions, the boiling temperature of the test substance was not determinable, as the test substance decomposed at temperatures above 140ºC without boiling (Sydney 2002).

Key value for chemical safety assessment
Additional information
Not determinable, as the test substance decomposed >140ºC, without boiling.
