Description
Styrene is a colorless or yellow, sweet odor liquid with a penetrating odor. It is produced during alkylation of benzene with ethylene. It is highly reactive and polymerizes rapidly with a violent explosive reaction. This demands proper handling, transportation, and storage by adding polymerization inhibitors in adequate quantities during these operations. Styrene monomer has been extensively used in the manufacture of chemical intermediates, fi lling components, plastics, styrene, styreen.
