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).
