Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
ca. 325 °C
Remarks on result:
other: +/- 10ºC

Any other information on results incl. tables

The lowest temperature giving a positive effect was 329ºC

The injected volume was 200ul, the ignition delay was 25s. At a temperature of 324ºC no ignition was observed. Therefore after rounding-off to the next-lower multiple of 5ºC:

Auto-Ignition temperature of 3-Butyne-2-ol: 325 +/- 10ºC
