- 260 °C
- Atm. press.:
- 101.325 kPa
Applicant's summary and conclusion
- Conclusions:
- The lowest temperature giving a positive effect was 264 °C. The injected volume was 100 µL, the ignition delay was 25 s. At a temperature of 259 °C no ignition was observed. Therefore, after rounding-off to the next lower multiple of 5 °C,
Auto-ignition temperature of Menthene, -1, Para was 260 ± 10 °C. - Executive summary:
The auto-ignition temperature of Menthene, -1, Para was determined in a SUR BERLIN oven, equipped with a 250 mL glass ignition vessel according to DIN 51794.
The lowest temperature giving a positive effect was 264°C. The injected volume was 100µL, the ignition delay was 25 s. At a temperature of 259°C no ignition was observed.
Therefore, after rounding off to the next-lower multiple of 5°C the auto-ignition temperature of Menthene, -1, Para was 260±10°C.
