EC number: 240-241-0 | CAS number: 16088-62-3
Auto flammability
Administrative data
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2002
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The result was obtained from a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable.
Data source
Reference
- Reference Type:
- review article or handbook
- Title:
- Unnamed
- Year:
- 2 002
Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: DIN 51794
- GLP compliance:
- no
Test material
- Reference substance name:
- propylene oxide
- IUPAC Name:
- propylene oxide
- Reference substance name:
- Methyloxirane
- EC Number:
- 200-879-2
- EC Name:
- Methyloxirane
- Cas Number:
- 75-56-9
- IUPAC Name:
- 2-methyloxirane
- Details on test material:
- Test material was racemate from both R(+) and S(-) propylene oxide. This endpoint is not measured / determined with enantio-selective sensors.
Therefore the S(-) value is identical to the racemate endpoint.

Results and discussion
Auto-ignition temperature (liquids / gases)
- Auto-ignition temperature:
- 420 °C
- Remarks on result:
- other: The lower value of the two reliable study endpoints was selected as a worst case.
Relative self-ignition temperature (solids)
- Relative self-ignition temperature:
- 420 °C
- Remarks on result:
- other: The lower value of the two reliable study endpoints was selected as a worst case.
Any other information on results incl. tables
Autoignition temperatures of 420°C (Elm, cited in Ullmans Encyklopädie der technischen Chemie, 1980) and 430°C (BASF AG, 1993) were reported. Both were conducted to an accepted Annex V test method (DIN 51794) although the actual test data were not provided. A value of 465°C (quoted in the NFPA handbook, 1994) could not be assigned.
Applicant's summary and conclusion
- Conclusions:
- An auto ignition temperature of 420°C was determined in a reliable study conducted according to an appropriate test protocol. No further details are
available.
