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:
OECD Guideline 103 (Boiling Point)
Qualifier:
according to
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.
