Description of key information

The substance has an auto ignition temperature of 643°C.  No information on atmospheric pressure reported.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
643 °C

Additional information

Information regarding auto flammability of DAA was sourced from two separate handbooks. CRC Handbook of Chemistry and Physics (81st Ed.) and Fire Protection Guide to Hazardous Materials (13th Ed.), which are known to contain peer-reviewed data of Klimisch-2 reliability report that the substance has an auto ignition temperature of 643°C. This value is above boiling point of 167.9°C, and representsthe lowest temperature at which vapours of DAA will spontaneously ignite in a normal atmosphere without an external source of ignition. No information on atmospheric pressure reported.
