Product Usage

Cumyl Hydroperoxide, also known as Cumene Hydroperoxide, with CAS No. 80-15-9, chemical formula C₉H₁₂O₂ and molecular weight 152.2, appears as a colorless to pale yellow transparent oily liquid. It is an organic peroxide with strong oxidizing properties and free radical initiating activity. Its core application is in the field of chemical synthesis, serving as a key intermediate in the production of phenol and acetone by the cumene process, which is the main global production method of phenol and acetone, and the products are widely used in downstream industries such as plastics and pharmaceuticals. Meanwhile, as an efficient free radical initiator, it is widely used in emulsion, solution and bulk polymerization reactions of polymers such as polystyrene and polymethyl methacrylate, and can also be used as a curing agent for unsaturated polyester resins. In addition, it is used in oxidation reactions in organic synthesis, such as alkene epoxidation and sulfide oxidation, and is an indispensable special chemical raw material in the fields of fine chemicals and polymer materials.
