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:
- November 28 - 29, 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)
- Deviations:
- no
- GLP compliance:
- no
- Specific details on test material used for the study:
- Purity test date: 20/10/2017
Expirty date: 18/04/2018 - Key result
- Auto-ignition temperature:
- 265 °C
- Atm. press.:
- 1 010 hPa
- Conclusions:
- The autoignition temperature (liquids) for 2-(2-methylpropoxy)ethanol was found to be 265 °C at 1010 hpa.
- Executive summary:
An experiment was undertaken in line with ASTM E659-14 (Standard Test Method for Autoignition Temperature of Liquid Chemicals) to determine the autoignition temperature of 2-(2-methylpropoxy)ethanol. The appearance of a flame within the flask and a rise in temperature indicated that auto-ignition had taken place. The lowest internal flask temperature at which hot-flame ignition occurred (i.e. the autoignition temperature) for 2-(2-methylpropoxy)ethanol was 265 °C at an atmospheric pressure of 1010 hpa.
