Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Well-documented guideline study on a well defined test substance.
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
>= 182.27 - <= 183.61 °C
Remarks on result:
other: Substance does not boil.
Conclusions:
The test substance does not boil; instead the test substance decomposes. This is noted by the exotherm in the DSC curve and is confirmed by hot stage microscopy whereby the test substance was heated at 10°C/min to 300°C. Note that test substance went from clear to very hazy ~183 °C indicating decomposition. The DSC curve below shows the decomposition onsets on duplicate runs at 182.27°C and 183.61°C.

Description of key information

The boiling point of the test material was assessed according to OECD Test Guideline 103. The test substance does not boil; instead the test substance decomposes. The DSC curve shows the decomposition onsets on duplicate runs at 182.27 and 183.61 °C.

Key value for chemical safety assessment

Additional information

The boiling point of the test material was assessed according to OECD Test Guideline 103 using a pierced Al DSC pan. Prior to analysis, the test substance was heated in a vacuum oven at 60 °C to constant weight to remove any residual volatiles (1-butanol). The test substance specimens were scanned at 10 °C/min from 20 to 300 °C.  An indium standard was used to calibrate the instrument; the indium standard was also scanned at 10 °C/min. 

The test substance does not boil; instead the test substance decomposes. The DSC curve shows the decomposition onsets on duplicate runs at 182.27 and 183.61 °C.
