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.

Key value for chemical safety assessment

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).
