Description

Insoluble in water and less dense than water. Contact may cause irritate skin, eyes, and mucous membranes. May be toxic by ingestion.;Styrene monomer, stabilized appears as a clear colorless to dark liquid with an aromatic odor. Vapors heavier than air and irritating to the eyes and mucous membranes. Subject to polymerization. If the polymerization takes place inside a closed container, the container may rupture violently. Less dense than water and insoluble in water. Used to make plastics, paints, and synthetic rubber.;GasVapor; Liquid; PelletsLargeCrystals; PelletsLargeCrystals, Liquid;Liquid;Liquid;COLOURLESS-TO-YELLOW OILY LIQUID.;COLOURLESS SOLID IN VARIOUS FORMS.;Colorless to yellow, oily liquid with a sweet, floral odor.;Colorless to yellow, oily liquid with a sweet, floral odor.

Stability

Stable under recommended storage conditions. Test for peroxide formation before distillation or evaporation. Test for peroxide formation or discard after 1 year.;On exposure to light and air it slowly undergoes polymerization and oxidation with formation of peroxides, etc..;It is a storage hazard above 32 °C.;... Styrene is stabilized by a polymerization inhibitor (often tertbutylcatechol). If this is not present in adequate concn, styrene can polymerize and explode its container. The polymerization is also speeded up by temperatures above 66 °C (150 °F).
