Endpoint summary
Administrative data
Description of key information
Chlorobenzene is a liquid of medium volatility, with low potential for bioaccumulation, and low solubility in water.
It is classified as a FLAMMABLE LIQUID, in category 3, but no other physical hazard is anticipated.
Based on chemical nature and low viscosity, potential for Aspiration hazard should be further investigated.
Additional information
The melting point of chlorobenzene is -46°C (Römpp Online, 2008)
Chlorobenzene boiling point is 131 -132 °C (The Merck Index, 2006, Römpp Online, 2008 ).
The density of chlorobenzene is, according to The Merck Index, 2006 at 20 °C 1.107 g/cm³.
Particle size distribution: the study does not need to be conducted because the substance is marketed or used in a non solid granular form (liquid).
Chlorobenzene vapor pressure is 15.81 hPa at 25 °C (BUA report, 1990)
The highest, worst-case, n-Octanol/water partition coefficient reported for Chlorobenzene is logKow = 3,00 (RP-HPLC method; BUA report, 1990)
The highest, worst-case, Chlorobenzene´s water solubility is 0.538 g/L at 25 °C (calculated; BUA report, 1990)
Chlorobenzene is freely soluble in alcohol, benzene, chloroform, ether (Merck index, 2006).
No surface activity is anticipated or desired.
Chlorobenzene flash point is 28 °C (Merck Index 2006).
Chlorobenzene ignition temperature of chlorobenzene is 590 °C (BUA report 54, 1990).
No flammability if contact with air or water, no self-heating, explosive, oxidising or self-reactive properties are anticipated.
Stability in organic solvents is considered not to be critical.
Dissociation constant is irrelevant.
Chlorobenzene's viscosity is 0.756 mPa*s at ca 20°C (Kirk-Othmer, 2006)
