| | 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. | | Uses | As a reactive monomer in the production
of polymers and coatings. | | Uses | Vinyltoluene Monomer (m- and p- mixture) (stabilized with TBC) can be used to treat inflammation. | | 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. | | Flammability and Explosibility | Notclassified | | 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. | | Carcinogenicity | The IARC has determined that there is
evidence suggesting the lack of carcinogenicity of vinyltoluene in experimental animals and
inadequate evidence in humans. | | 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. |
