Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- ASTM E659 (Standard test method for autoignition temperature of liquid chemicals)
- Version / remarks:
- ASTM Method E659-15 “Autoignition Temperature of Chemicals” and Council Regulation (EC) No 440-2008 appendix A.15 “Auto-ignition Temperature (Liquids and Gases).
- GLP compliance:
- no
- Specific details on test material used for the study:
- The commercial product containing the "substance", Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487 -01 -9, EC Number 275 -532 -1, in organic solvents, methanol and isopropanol (ca. 32%) was utlised for this study. Prior to this study being undertaken, these solvents were removed by, firstly, leaving the sample under a stream of nitrogen to remove the majority of the solvent(s) and, secondly, evaporating the remaining residual solvent(s) under vacuum at 60 degress C to constant dried weight of the test item. After solvent removal the substance was identified to be a yellow viscous liquid / wax like solid.
- Key result
- Auto-ignition temperature:
- ca. 215 °C
- Atm. press.:
- 100 kPa
- Remarks on result:
- other: The auto-ignition temperature of the Test Item was determined to be 225 deg C at 102 kPa and 215 deg C when normalised to a barometric pressure of 100 kPa
- Conclusions:
- The auto-ignition temperature of the Test Item (Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487-01-9, EC Number 275-532-1) was determined to be 225 deg C at 102 kPa and 215 deg C when normalised to a barometric pressure of 100 kPa.
- Executive summary:
The auto-ignition temperature of the test item (Quaternary ammonium compounds, di-C12-18-alkyldimethyl, nitrites, CAS Number 71487-01-9, EC Number 275-532-1) was investigated in a study conducted in accordance with ASTM Method E659-15 “Autoignition Temperature of Chemicals” and Council Regulation (EC) No 440-2008 appendix A.15 “Auto-ignition Temperature (Liquids and Gases).
This study is assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al (1997).
Under the conditions of the study the auto-ignition temperature of the Test Item was determined to be 225 deg C at 102 kPa and 215 deg C when normalised to a barometric pressure of 100 kPa.
