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.
