Description and Uses
Cumene hydroperoxide, an organic peroxide,is a colorless to pale yellow to green liquid. Mild odor.Molecular weight=152.21; Boiling point=153℃;Freezing/Melting point=2 10℃. It explodes on heating;Flash point=79℃. Its explosive limits are: LEL=0.9%;UEL=6.5%. Hazard Identification (based on NFPA-704 MRating System): Health 1, Flammability 2, Reactivity 4(Oxidizer). Slightly soluble in water.
Cumene hydroperoxide is used in the preparation of polystyrene nanocapsules. It acts as a curing agent for polyester resins and as an oxidizer in organic chemical reactions. It serves as an initiator for radical polymerization especially for acrylate and methacrylate monomers. It also employed as an intermediate in the cumene process for developing phenol and acetone from benzene and propene. Further, it is used as an epoxidation reagent for allylic alcohols and fatty acid esters. In addition to this, it is also used to prepare methylstyrene, acetophenone and cumyl alcohol.
