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:
- 04.06.2019-03.07.2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline

- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Name: Pentaerythritol tetrabenzoate
Appearance: off-white solid
Composition: Pentaerythritol tetrabenzoate >96%
CAS No.: 4196-86-5
EINECS-No.: 224-079-8
Molecular formula: C33H28O8
Molecular weight: 552.576 g/mol
Purity: >96%
Homogeneity: homogeneous
Expiry date: Nov. 2018
Storage: Room Temperature (20 ± 5°C) - Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 375.51 °C
- Remarks on result:
- not determinable
- Conclusions:
- As the test item decomposes the determination of boiling point of Pentaerythritol tetrabenzoate is technically not feasible.
- Executive summary:
The determination of the melting / boiling point was determined via DSC (differential scanning calorimetry) In both DSC measurements one endothermic event was detected. In accordance to the pre-test the first endothermic event can be identified as melting point, evaluated with the onset function. In the further process a turbulent baseline was observed which probably supposed to be beginning of decomposition. In the pre-test for boiling point a colour change was observed, which was a sign of decomposition also the colour change of the test item in the crucible after DSC measurement.
The beginning of decomposition was evaluated with the event marker function of the DSC software.
As the test item decomposes the determination of the boiling point of Pentaerythritol tetrabenzoate is technically not feasible.
