Description of key information
The auto ignition temperature of Olaflur was determined to be 400 °C (i.e. 673.15 K), the auto-ignition temperature of solvent-free Olaflur was determined to be 390 °C (i.e. 663.15 K).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 400 °C
Additional information
The preliminary results indicate that the auto-ignition temperature of Olaflur is around 400 °C.
During the main test the auto ignition temperature was determined to be 400 °C (i.e. 673.15 K)
Repetition of auto-ignition temperature determination with solvent-free Olaflur:
In order to eliminate a possible effect of ethanol and water the measured sample was treated in the following manner: The Olaflur sample was put in a rotary evaporator and the residual solvents (ethanol and water) were distilled off under vacuum of 0.08 mbar and 85 °C. After 11 hours no more weight loss could be observed. The total loss of weight was 11.4 %. With this sample the following preliminary results were obtained: 380 °C = no ignition, 400 °C = ignition
During the main test the auto-ignition temperature of solvent-free Olaflur was determined to be 390°C (i.e. 663.15 K).
Comparison of the results
The difference of 10 °C (390 °C vs. 400 °C) shows that ethanol does not have a significant influence on auto-ignition temperature. It is more likely that the lesser water content makes the ignition of the substance easier.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
