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.??
2-Chlorostyrene is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.?? ??
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.??? ?? ??
Highly flammable. Insoluble in water.?? ???
2-Chlorostyrene may be sensitive to heat or prolonged exposure to light. 2-Chlorostyrene may polymerize.???
Central nervous system impairment and peripheral neuropathy.????
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.
????
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 .??? ??
In organic synthesis; in the preparation of specialty polymers.?? ??
