Cumene hydroperoxide

It is typically used as an oxidizing agent. Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and cumyl alcohol. It has a role as an oxidising agent, an environmental contaminant and a Mycoplasma genitalium metabolite.

It derives from a hydride of a cumene. CUMENE HYDROPEROXIDE is a strong oxidizing agent. May react explosively upon contact with reducing reagents.

Violent reaction occurs upon contact with copper, copper alloys, lead alloys, and mineral acids. Contact with charcoal powder gives a strong exothermic reaction. Cumene (isopropylbenzene), required for the Hock process, is produced by alkylation of benzene with propylene over a solid phosphoric acid catalyst (UOP-process).

Cumene is oxidized with oxygen in air in the liquid phase to cumene hydroperoxide (CHP). Cumene Hydroperoxide is a colorless to pale yellow liquid with a strong odor. It is used to make Acetone and Phenol, as a curing agent, and a polymerization catalyst. In the first step, the terminal hydroperoxy oxygen atom is protonated.

Acetone and phenol are produced by the so-called cumene process, which proceeds via cumene hydroperoxide. Many epoxides are prepared using hydroperoxides as reagents, such as the Halcon process for the production of propylene oxide. The Sharpless epoxidation is a related reaction conducted on laboratory scale. This oxidizing agent is commercially available with a purity of ~. M solution in benzene has a half-life of hours at 1C.

The decomposition products of cumene hydroperoxide are methylstyrene, acetophenone, and cumyl alcohol. It is a polymerization inhibitor, a strong oxidizing agent, and a reagent for organic peroxide manufacturing. Colorless liquid with a sharp, penetrating, aromatic odor.

Class IC Flammable Liquid: Fl. Only select Registry of Toxic Effects of Chemical Substances (RTECS) data is presented here. Cumene hydroperoxide - Investigated as a mutagen, primary irritant, and tumorigen. See actual entry in RTECS for complete information.

It is produced via the oxidation of cumene with air in the presence of aqueous sodium carbonate as the catalyst (Figure 2). CHP is primarily used in the production of acetone and phenol. Hydroperoxides or peroxols are compounds containing the hydroperoxide functional group (ROOH).

If the R is organic, the compounds are called organic hydroperoxides. Such compounds are a subset of organic peroxides, which have the fromula ROOR. In peroxide One category is represented by cumene hydroperoxide , an organic compound used as a polymerization initiator and as a source of phenol and acetone, and peroxysulfuric aci an inorganic compound used as an oxidizing agent. The other category includes di-tert-butyl peroxide and ammonium peroxydisulfate, both used as initiators. Peroxide initiators include MEKP and other ketone peroxides, t-butyl perbenzoate, t-butyl hydroperoxide , cumene hydroperoxide , dicumyl peroxide, and BPO paste.

Thirteen companies have been identified as producers of cumene hydroperoxide in the United States. In this process, cumene hydroperoxide and sulfuric acid are reacted in a reflux cooled reactor the products of which are transported under inhibited reaction conditions to a plug flow reactor, and are reacted to produce phenol, DMK, and AMS. The thermal decomposition and runaway reaction of cumene hydroperoxide (CHP) in cumene were studied by thermal analysis and by using the VSP-II adiabatic calorimeter.

Decomposition kinetics were determined in various CHP concentrations in cumene. Fp 1°C storage temp.
