It is commonly used as a polymerization initiator for the production of various polymers, including polyethylene, polypropylene, and polystyrene.PropertiesCAS 68453-56-5 has a molecular weight of 338.5 g/mol and a melting point of 70-80??C. It is highly soluble in organic solvents, such as acetone, benzene, and toluene, but insoluble in water. It has a density of 1.08 g/cm3 and a boiling point of 140-150??C.SynthesisCAS 68453-56-5 is typically synthesized through the reaction of 1,3-dibromo-5-tert-butylbenzene with isopropyl alcohol in the presence of a base, such as potassium hydroxide or sodium hydroxide. The reaction produces 1,3-Bis(tert-butylperoxyisopropyl)benzene as the main product, along with other byproducts.CAS 68453-56-5 is primarily used as a polymerization initiator for the production of various polymers, including polyethylene, polypropylene, and polystyrene. It is also used as a crosslinking agent for rubber and plastics, as well as a curing agent for epoxy resins.SafetyCAS 68453-56-5 is a highly reactive and combustible substance that can cause severe burns and eye damage upon contact. It may also cause respiratory irritation and allergic reactions. It should be handled with extreme care and stored in a cool, dry, and well-ventilated area away from heat sources and oxidizing agents. Personal protective equipment, such as gloves, goggles, and a respirator, should be worn when handling this substance.
