Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure = 0.00004 Pa at 25°C, 0.32 Pa at 140°C, 8.4 Pa at 200°C (extrapolated)
The substance is NOT considered as a Volatile Organic Compound (V.O.C.) according to Directive 1999/13/EC criteria.

Additional information

A GLP study was conducted for the determination of the vapour pressure of the substance 99422018, with vapour pressure balance method. Vapour pressure measurements were recorded between 54 and 80°C (solid substance). Value at 25°C was extrapolated by calculation from the linear regression of log P = f(T).

The values extrapolated at 140 and 200°C are merely indicative as it seems unlikely that the equation log P = f(T) stays monotonous during/after melting (see melting range).
