Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to literature (BUA report, 1990; secondary source), Chlorobenzene vapor pressure is:
at 20 °C: 11.73 hPa (Neumüller O-A, 1979. 8. Aufl., Bd 1, Frank´sche Verlagsbuchhandlung, Stuttgart, p 715)
at 22.2 °C: 13.3 hPa (Ullmann´s encyclopedia of industrial chemistry, fifth, completely revised edition, band A6, VHC Verlagsgesellschaft mmH Weinheim, 328-340)
at 25 °C: 15.81 hPa (J. Phys. Chem Ref. Data 10, 1175-1193)


 


Medium volatility (based on volatility bands criteria for occupational exposure (Chesar / ECETOC TRA), 0,5-10 kPa).

Key value for chemical safety assessment

Vapour pressure:
15.8 hPa
at the temperature of:
25 °C

Additional information

Several literature sources were available and provide consistent vapour pressure values, ranging between 1,0 and 1,6 kPa at 20-25°C, for the substance; values at temperatures other than ambient (-43 to +132°C) are also presented. The BUA report value, considered as a reliable source and including the prefered temperature of 25°C, was chosen as key.
