Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2016-10-24 until 2017-05-03
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- internal method 2011-0466801-94D (DTA/DSC), which corresponds to OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No: 102 and to Council Regulations EC No 440/2008, Guideline Part A– Methods for the Determination of Physico-Chemical Properties, A.1.
- Principles of method if other than guideline:
- Samples of the test item and of a reference material are subjected to the same controlled temperature programme. The difference in energy input necessary to maintain identical temperatures between the test item and the reference material is recorded. When the test item undergoes a phase transition, the corresponding change of enthalpy gives an endothermic (melting) or exothermic (freezing) deviation from the base line of the temperature and heat flow record.
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Date of receipt: 2014-01-15
Expiry date: 2017-03-07 - Remarks on result:
- not determinable
- Remarks:
- Since no endothermic signal could be detected there is no indication for a melting point.
- Conclusions:
- Due to decomposition of the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane- 2,1-diyl) trisprop-2-enoate determination of the melting point was not possible.
- Executive summary:
Melting point to the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate was determined via Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC). After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item. Due to decomposition of the test item the determination of the melting point was not possible.
Reference
At room temperature the substance is solid.
Between 25 °C and 450 °C several exothermic phases in different temperature ranges were observed.
A first exothermic phase was detected between approx. 85 °C and 125 °C which could indicate a chemical change and / or decomposition of the test item. Between approx. 180 °C and 270 °C and approx. 295 °C and 350 °C two further exothermic effects were observed.
After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item.
Description of key information
Due to decomposition of the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate determination of the melting point was not possible.
Key value for chemical safety assessment
Additional information
After the heating process a solid black residue remains in the crucible which indicates decomposition of the test item.
