Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Flash point (closed-cup) of diethylenetriamine is 96.7 °C at 101.3 kPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
369.7 K

Additional information

Several sources report various values of flash-point, using both open-cup and closed-cup techniques. Because these values are close to the cut-off value of 100 °C, a definitive measurement was performed using the preferred Pensky-Martens closed-cup technique with a high purity (99 +%) sample of commercial diethylenetriamine. This preferred flash point value is 96.7 °C, and therefore the substance is not classified as a flammable liquid.
