Results and discussion

Auto-ignition temperature (liquids / gases)
Key result
Auto-ignition temperature:
405 °C
Remarks on result:
other: ± 5ºC

Any other information on results incl. tables

The lowest temperature giving a positive effect was 409ºC

The injected volume was 100ul, the ignition delay was 12s. At a temperature of 404ºC no ignition was observed. Therefore, after rounding-off to the next-lower multiple of 5ºC:

Auto-ignition temperature of Hydroxy DHLL: 405 ± 5ºC

Applicant's summary and conclusion

Conclusions:
The lowest temperature giving a positive effect was 409ºC
The injected volume was 100µl, the ignition delay was 12s. At a temperature of 404ºC no ignition was observed. Therefore, after rounding-off to the next-lower multiple of 5ºC:
Auto-ignition temperature of Hydroxy DHLL: 405 ± 5ºC
Executive summary:

Auto-ignition temperature of Hydroxy DHLL: 405 ± 5ºC
