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
