Applicant's summary and conclusion
- Conclusions:
- The Auto-ignition temperature of lsopropyl isopropenyl benzene (MonoPEB) was determined according to the DIN 51794.
The lowest temperature giving a positive effect was 444 °C. The injected volume was 100 µL, the ignition delay was 8s. At a temperature of 439°C no ignition was observed.
Therefore, after rounding-off to the next-lower multiple of 5°C:
Auto-ignition temperature of lsopropyl isopropenyl benzene (MonoPEB): 440 ± 5°C - Executive summary:
The Auto-ignition temperature of lsopropyl isopropenyl benzene (MonoPEB) was determined in a SUR BERLIN oven, equipped with a 250 ml glass ignition vessel according to the DIN 51794.
The lowest temperature giving a positive effect was 444 °C. The injected volume was 100 µL, the ignition delay was 8s. At a temperature of 439°C no ignition was observed.
Therefore, after rounding-off to the next-lower multiple of 5°C:
Auto-ignition temperature of lsopropyl isopropenyl benzene (MonoPEB): 440 ± 5°C
