- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 317 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: +- 2°C
- Conclusions:
- The data from this experimental result shows that the boiling point of the test substance is 317 °C± 2 °C.
- Executive summary:
The data from this experimental result shows that the boiling point of the test substance is 317 °C ± 2 °C.
- Endpoint:
- boiling point
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: no information available whether the calculation model is validated for the substance under investigation
- Principles of method if other than guideline:
- The boiling point of imidazolium compounds, 2-(C17 and C17-unsatd. alkyl)-1-[2-(C18 and C18-unsatd. amido)ethyl]-4,5-dihydro-1-methyl, Me sulfates was calculated using EPIWIN v3.20, MPBPWIN v1.42.
- Type of method:
- other: calculation
- Key result
- Boiling pt.:
- 864.62 °C
- Conclusions:
- The boiling point of imidazolium compounds, 2-(C17 and C17-unsatd. alkyl)-1-[2-(C18 and C18-unsatd. amido)ethyl]-4,5-dihydro-1-methyl, Me sulfates was calculated using EPIWIN v3.20, MPBPWIN v1.42. The calculation yielded a value of 864.62°C. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the result should be treated with care.

The DSC curves showed a large endothermic peak in the range between 293 -337 °C. The heat flow in the peak area was determined to be approximately 110 J/g, which lies within the range of typicality for the boiling process of an organic substance. The boiling point was therefore identified as the temperature where the observed signal is at its peak, 317 °C.
A boiling point of 864.62°C was calculated using EPIWIN v3.20, MPBPWIN v1.42. Due to missing information about the applicability of the calculation model in respect to the substance under investigation the result should be treated with care.
For the two differential scanning calorimetry tests, a black melt remained at the end of the test.
Description of key information
The boiling point of the oleic-acid based IQAC, DMS quaternised is 317 °C ± 2 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 317 °C
Additional information
The DSC curves showed a large endothermic peak in the range between 293 -337 °C. The boiling point was therefore identified as the temperature where the observed signal is at its peak, 317 °C.
