At 20 0C, 2-chlorophenol is a liquid denser than water and moderately volatile.
Characterized as very soluble, once dissolved, it volatilizes slowly and adsorbs moderately to
organic matter. In the event of a spill, this compound will evaporate but the majority of the
material will enter into the soil or migrate into a water course. Once it encounters water (surface
or subsurface), 2-chlorophenol will dissolve (primarily) or sink until it reaches an impermeable
surface. The liquid 2-chlorophenol that accumulates in a saturated zone will dissolve rapidly before
it slowly volatilizes. The adsorbed 2-chlorophenol will disappear relatively quickly, liberating
contamination primarily in the dissolved phase, as well as in a gaseous state. The resulting
dissolved plume can be relatively large whereas the gaseous plume will be relatively small in
size.
2-chlorophenol should be handled with care, as it is toxic, corrosive and flammable.
Chlorinated phenols are manufactured by the chlorination of phenol. Chlorophenols have
been used as biocides and for the production of more chlorinated phenols. The chlorophenols have
also been used as antiseptics, although they have largely been replaced by other chemical
antiseptics. 2-chlorophenol is a chemical intermediate in phenolic resins and is used as a solvent
for polyester fibers.
