Chemical Properties
2-Chlorostyrene, also called o-Chlorostyrene, is a flammable liquid that ranges in color from colorless to light yellow. It is used in the manufacture of polychlorostyrene which is a clear, colorless plastic with good foaming, heat distortion and flame-retardant properties.
Uses
2-Chlorostyrene is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.
Preparation
o-Chlorostyrene is commercially produced as a monomer from o-chloroethylbenzene by an oxidation technique. p-Chlorostyrene is also produced as a mixture with o-chlorostyrene.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
2-Chlorostyrene may be sensitive to heat or prolonged exposure to light. 2-Chlorostyrene may polymerize.
Hazard
Central nervous system impairment and
peripheral neuropathy.
Health Hazard
By analogy to styrene, ochlorostyrene
is expected to cause central
nervous system depression at extremely high
concentrations and possibly irritation of the
eyes, nose, and mucous membranes.
There are no reports of adverse effects in
humans.
Fire Hazard
2-Chlorostyrene is combustible.
Safety Profile
A skin and eye irritant.
When heated to decomposition it emits
toxic fumes of Cl-. See also
CHLORINATED HYDROCARBONS,
AROMATIC .
Potential Exposure
In organic synthesis; in the preparation of specialty polymers.
Shipping
UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required.
Incompatibilities
Contact with elevated temperatures, strong oxidizers, strong bases; or acids may cause fire or explosion. May form peroxides; explosive polymerization may occur.
