Name:
Unnamed
Type:
Constituent
Type:
Constituent
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 R(+) 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.
