Hazard InformationBack Directory
[Chemical Properties]

colourless liquid with a strong and unpleasant odour
[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.
[Fire Hazard]

Flash Point (°F): 137 ℃, 125 ℃; Flammable Limits in Air (%): 0.8-11; Fire Extinguishing Agents: Water fog, foam, carbon dioxide, or dry chemical; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Containers may explode or rupture in fires due to polymerization; Ignition Temperature (°F): 914; Electrical Hazard: Not pertinent; Burning Rate: 6.0 mm/min.
[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).
[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.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Do not induce vomiting.
[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.
[Flammability and Explosibility]

Notclassified
[Carcinogenicity]

The IARC has determined that there is evidence suggesting the lack of carcinogenicity of vinyltoluene in experimental animals and inadequate evidence in humans.
