Applicant's summary and conclusion
- Conclusions:
- The Auto-ignition temperature of TBPK was determined according to the DIN 51794.
The lowest temperature giving a positive effect was 439°C. The injected volume was 100 µL, the ignition delay was 24 s. At a temperature of 434°C no ignition was observed.
Therefore, after rounding-off to the next-lower multiple of 5°C:
Auto-ignition temperature of TBPK: 435±5°C - Executive summary:
The Auto-ignition temperature of TBPK 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 439°C. The injected volume was 100 µL, the ignition delay was 24 s. At a temperature of 434°C no ignition was observed.
Therefore, after rounding-off to the next-lower multiple of 5°C:
Auto-ignition temperature of TBPK: 435±5°C
