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:
- 2003-04-25 to 2004-05-28
- 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)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Auto-ignition temperature:
- 500 °C
- Atm. press.:
- 1 023 hPa
- Remarks on result:
- other: +/- 3°C
- Conclusions:
- Auto-ignition temperature (ASTM E659-78): 500 +/- 3°C (1023 hPa)
- Executive summary:
The auto-ignition temperatue was determined for 1-chloro-2,3-dimethylbenzene according to ASTM E659-78 compliant with GLP.
The test item (approx. 100 µL) was placed in a heated 0.5-L flask, and the flask was observed in the dark. This procedure was repeated, varying the temperature, and the lowest temperature that the test item was observed to ignite was the autoignition temperature. The "ignition delay time", the time between addition of test item to the flask and ignition, was also recorded.
Results obtained:
Auto-ignition temperature: 500 +/- 3 °C at 1023 hPa;
Ignition delay time: 21 seconds.
Reference
