Conclusions:

Commercially available auto-ignition temperature apparatus was used for the determination
of the degree of auto-ignitability of 1,3-dichloro-2-propanol.
The test item is auto-ignitable with an auto-ignition temperature of 550°C.
The atmospheric pressure was 1014 and 1013 hPa.

Executive summary:

The objective of this study was to determine the degree of auto-ignitability in terms of the auto-ignition temperature.

The auto-ignition temperature was 550⁰C at 1013 and 1014 hPa.
