kumüülhüdroperoksiid

Kumüülhüdroperoksiid, also known as cumene hydroperoxide or CHP, is an organic peroxide with the chemical formula C₆H₅C(CH₃)₂OOH. It is a colorless to pale yellow liquid that is unstable and can decompose violently if heated or subjected to shock. CHP is primarily used as an intermediate in the industrial production of phenol and acetone via the cumene process. In this process, cumene (isopropylbenzene) is oxidized to form kumüülhüdroperoksiid, which is then cleaved in the presence of an acid catalyst to yield phenol and acetone. This method is the dominant industrial route for producing these two important chemicals.

Kumüülhüdroperoksiid is also employed as an initiator in polymerization reactions, particularly for certain types of plastics and synthetic rubbers. Its ability to generate free radicals upon decomposition makes it effective in starting and propagating chain growth. Additionally, it finds niche applications as a bleaching agent and as a curing agent for resins. Due to its hazardous nature, CHP is typically handled with extreme caution, requiring specialized storage and transportation procedures to prevent accidents. It is classified as a dangerous good and is subject to strict regulations regarding its production, use, and disposal.
