2-Chlorostyrene Usage And Synthesis

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.
