EC number: 457-320-2 | CAS number: -
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:
- 1999-11-10 to 2000-01-07
- 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:
- method according to Siwoloboff
- Remarks:
- (and subsequently differential scanning calorimetry)
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 125 °C
- Remarks on result:
- other: Differential scanning calorimetry
- Decomposition:
- ambiguous
- Decomp. temp.:
- >= 280 °C
- Remarks on result:
- other: Modified Siwoloboff method
- Conclusions:
- In a GLP study conducted according to OECD guideline 103, the boiling temperature of EC# 434-650-5 was not determinable as the test material decomposed at temperatures above 125oC without boiling
- Executive summary:
In a GLP study conducted according to OECD guideline 103, the boiling temperature of EC# 434-650-5 was investigated.
Using the modified Siwoloboff method, the test material appeared to decompose when heated to approximately 280oC, although the dark colour precluded reliable assessment. Differential scanning calorimetry suggested that the material decomposed above 125oC without boiling, the end product being a black, crispy solid.
In conclusion, the boiling temperature of EC# 434-650-5 was not determinable as the test material decomposed at temperatures above 125oC without boiling.
- Endpoint:
- boiling point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 125 °C
- Remarks on result:
- not determinable
- Remarks:
- Decomposed above 125 oC without boiling
- Conclusions:
- In a GLP study conducted according to OECD guideline 103, the boiling temperature of EC# 434-650-5 was investigated.
Using the modified Siwoloboff method, the test material appeared to decompose when heated to approximately 280oC, although the dark colour precluded reliable assessment. Differential scanning calorimetry suggested that the material decomposed above 125oC without boiling, the end product being a black, crispy solid.
In conclusion, the boiling temperature of EC# 434-650-5 was not determinable as the test material decomposed at temperatures above 125oC without boiling. - Executive summary:
In view of the structural and chemical similarities, it is considered that the results of this study can be used for read-across to EC# 457-320-2.
