Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point

Currently viewing:

Administrative data

Endpoint:
boiling point
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid which decomposes before boiling
the study does not need to be conducted because chemical change occurred during the melting point study
Justification for type of information:
The physico-chemical data for the MOL-LUB substance is also provided to support the read-across of toxicological and ecological endpoints from the Source Substance (MOL-LUB) to XP 453 (Target Substance).
A full discussion of read-across and supporting data is given in the attached justification in Appearance / physical state / colour: XP 453.
Cross-reference
Reason / purpose for cross-reference:
reference to same study
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16/5/17
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The physico-chemical data for the MOL-LUB substance is also provided to support the read-across of toxicological and ecological endpoints from the Source Substance (MOL-LUB) to XP 453 (Target Substance).

Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
27-07-1995
Deviations:
no
GLP compliance:
no
Type of method:
capillary method
Key result
Melting / freezing pt.:
> 240 °C
Atm. press.:
1 atm
Decomposition:
yes
Decomp. temp.:
> 234 °C
Remarks on result:
not determinable
Conclusions:
During the course of heating, sample decomposition was observed, indicated by its color change from off-white to brown. The onset of the slow color change was observed at about 234°C. The sample remained solid and melting of the sample did not occur by 240°C.
