Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Study period:
2009-10-19 to 2009-12-10
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point)
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
GLP compliance:
no
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
4-(Methacryloyloxy) bezophenone 97.26 %
Benzophenone acetate: 1.95 %
Decomposition:
yes
Decomp. temp.:
ca. 256 °C

In the second run from room temperature to 400 °C, the same behaviour as in the first run is observable. Due to the decomposition of the sample near 256 °C, no boiling point can be determined at atmospheric pressure.

Conclusions:
No boiling point was detected prior to decomposition.
Executive summary:

No boiling point was detected prior to decomposition.
