Product Applications
Cumene Hydroperoxide is utilized in producing polystyrene nanocapsules. It functions as a curing agent for polyester resins and an oxidizing agent in organic chemical processes. It acts as an initiator for free-radical polymerization, particularly involving acrylate and methacrylate monomers. It is also used as an intermediate in the cumene process to produce phenol and acetone from benzene and propene. Additionally, it serves as an epoxidation reagent for allylic alcohols and fatty acid esters. Furthermore, it is employed in the production of methylstyrene, acetophenone, and cumyl alcohol.
