Description of key information

Calculated <0.0001 Pa at 25°C

Key value for chemical safety assessment

Additional information

The vapour pressure was measured and extrapolated using measured values by modified static method. The extrapolated value has been considered to be inaccurate as the measurement was carried out at high temperature 170°C. Thus, the vapour pressure was additionally calculated using recommended program SPARC v4.6. The calculation have been generated on the individual representative components of test substance and resulted as follows:

1.7 E-8 Pa for Di-alkyl-diphenylamine isomer

6.8 E-5 Pa for Mono-nonyl-diphenylamine isomer

It can be suggested that the vapour pressure of test substance was calculated to be <0.0001 Pa at 25°C.
