Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
ca. 190 °C
Remarks on result:
other: +/- 10ºC

Any other information on results incl. tables

The lowest temperature giving a positive effect was 194ºC

The injected volume was 400ul, the ignition delay was 60s. At a temperature of 189ºC no ignition was observed. Therefore after rounding-off to the next-lower multiple of 5ºC:

Auto-Ignition temperature of Neocaspirene Stage 1: 190 +/- 10ºC
