METHYLSTYRENE Usage And Synthesis

Chemical Properties

Colourless liquid with a strong and unpleasant odour. Very slightly soluble in water; soluble in methanol, ether. Combustible.

Chemical Properties

Vinyl toluene is a colorless liquid. Strong disagreeable odor. It consists of mixed meta-and para-isomers. The odor threshold is 50 ppm.

Uses

Solvent, intermediate.

General Description

A clear colorless liquid with an aromatic odor. Flash point 130°F. Density 7.5 lb /gal. Insoluble in water. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a container, the container may rupture violently. Inhibitor is usually tert-butyl catechol. Vapors heavier than air. Used as a solvent and to make other chemicals.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

METHYLSTYRENE polymerizes readily and exothermically [Handling Chemicals Safely 1980. p. 961].

Health Hazard

LIQUID: Irritating to skin and eyes. Harmful if swallowed.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Slow at ordinary temperatures but when hot may rupture container. Also polymerized by metal salts such as those of iron or aluminum; Inhibitor of Polymerization: Tertiary Butylcatechol (typically 10 to 50 ppm).

Safety Profile

Moderately toxic by ingestion and inhalation. An experimental teratogen. Human systemic effects by inhalation: eye and olfactory effects. Experimental reproductive effects. Mutation data reported. A skin and eye irritant. Flammable when exposed to heat or flame; can react vigorously with oxidrzing materials. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

(mixed isomers): Vinyl toluene is used in copolymers and as specialty monomer for paint, varnish, and polyester preparations; as a solvent and an organic intermediate.

Shipping

UN2618 Vinyltoluenes, stabilized, Hazard Class: 3; Labels: 3-Flammable liquid.

Incompatibilities

Vapors may form explosive mixture with air. Violent reaction with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, catalysts for vinyl polymerization, such as peroxides, strong acids; iron or aluminum salts. Usually inhibited with tert-butylcatechol to prevent polymerization.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
