Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Non GLP study, available as unpublished report, no restrictions, fully adequate for assessment.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- DSC analysis was used to determine the boiling point.
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- ca. 318.8 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 318.8 °C
- Conclusions:
- The test substance decomposes at boiling at 318.8°C.
- Executive summary:
In this study the boiling point of Tributyl(ethyl) phosphonium diethylphosphate was measured by DSC analysis.
Tributyl(ethyl) phosphonium diethylphosphate decomposes at boiling at 318.8°C
Reference
Two replicate DSC analyses were performed and provided the following results:
1: 316.7
2: 320.9
Mean value: 318.8.
The shape of the DSC curves indicates that Cyphos IL 169 has a boiling point and a decomposition simultaneously occurring. The endothermic peaks are broad with erratic behavior. This is an indication of onset of boil followed directly by decomposition. Decomposition is confirmed by analyzing the test substance at four different heating rates and observing a different onset each time. Boiling point is a first order reaction independent of heating rate. If the thermal event was a boiling point, the onset temperature would be consistent.
