- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 Nov 2019 - 05 Feb 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Lot/batch number of test material: 5674800
- Purity.: 91.8% (sum of two main components)
- Expiration date: 22 Jul 2020
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Store in well-ventilated place .Keep container tightly closed. Store locked up. - Key result
- Atm. press.:
- 985 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 150 °C
- Conclusions:
- MDP was determined to decompose at ca. 150°C before boiling at 985 hPa (OECD 103).
- Executive summary:
The decomposition temperature was determined by the differential scanning calorimetry (DSC). During the heating processes an exothermic effect was measured prior to the second endothermic effect, where thermal polymerisation was observed. Due to this effect it can be stated the test item has no boiling point up to its thermal polymerisation starting at a temperature of approximately 150 °C. The study was conducted in accordance with OECD 103 method under the scope of the the laboratory's ISO/IEC 17025 certification. Therefore, the study is considered reliable without restrictions.

- disregarded due to major methodological deficiencies
- Study period:

- Rationale for reliability incl. deficiencies:
- unsuitable test system

- reference to same study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- no
- Type of method:
- dynamic method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Lot/batch number of test material: M19-2405-001 - Key result
- Decomposition:
- yes
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- Test material was shown to thermally decompose before boiling
- Conclusions:
- MDP was determined to decompose before boiling.
- Executive summary:
The boiling point of MDP was examined using dynamic method. It was determined that MDP thermally decomposes prior to boiling. Due to methodological limitations the decomposition temperature was not determinable. Also, no stable reflux was observed during the experiment. Because of self-reaction at elevated temperatures, this method is unsuitable for measuring the boiling point of this substance. Therefore, the study is considered not reliable.

The test item showed an exothermic effect starting at a temperature of ca. 150 °C. The exothermic effect was directly followed by an endothermic effect starting at a temperature of ca. 220 °C. A second exothermic effect was observed starting at a temperature of ca. 370 °C. This exothermic effect was also directly followed by an endothermic effect starting at a temperature of ca. 400 °C. These results were compared to direct observations. Starting at a temperature of ca. 187 °C a formation of crystals or solid matter around the boiling capillary could be observed. This effect can be assigned to a thermal polyimersation of 1,10 decanediol dimethacrylate. The solid matter disappeared at a temperature of ca. 228 °C. Starting at a temperature of 270 °C a formation of crystals or solid matter could be observed again. At a temperature of 278 °C the test item foamed up and changed its colour from yellow to brownish. The colour of the test item turned to amber at a temperature of ca. 300 °C and only a small amount is left on the bottom of the capillary. At a temperature of 325 °C the residue turned to black. Up to a temperature of 400 °C the residue partially turned white to greyish. After the test a black residue remained at the bottom of the capillary.
Due to the fact that the test item showed an exothermic effect before its second endothermic effect, which can be assigned to its thermal polymerisation, it can be stated the test item has no boiling point up to its thermal polymerisation starting at a temperature of ca. 150 °C.

The sample was observed at a temperature of 118 °C and 1.0 mmHg to be solidifed. Prior in the test at 80 °C and 1.2 mmHg the sample was observed to be a liquid but not in a stable reflux.
Description of key information
MDP was determined to decompose at ca. 150°C before boiling at 985
hPa (OECD 103).
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 150 °C
Additional information
The study was conducted in accordance with OECD 103 method under the scope of the the laboratory's ISO/IEC 17025 certification. The decomposition temperature was determined by the differential scanning calorimetry (DSC). During the heating processes an exothermic effect was measured prior to the second endothermic effect, where thermal polymerisation was observed. Due to this effect it can be stated the test item has no boiling point up to its thermal polymerisation starting at a temperature of approximately 150 °C. The study was considered reliable without restrictions.
A second study was conducted, using dynamic method to evaluate the
boiling point of MDP. Because of self-reaction at elevated temperatures,
this method was unsuitable for measuring the boiling point of this
substance. Therefore, the study is considered not reliable.
