'''''tert''-Butyl hydroperoxide''' (tBuOOH) is the organic compound with the formula (CH₃)₃COOH. It is one of the most widely used [[hydroperoxides]] in a variety of [[oxidation]] processes, like the [[Halcon process]].<ref name=Patai>{{cite book |title= Syntheses and Uses of Hydroperoxides and Dialkylperoxides |editor1-first= Saul |editor1-last= Patai | author= Roger A. Sheldon |year= 1983 |publisher= John Wiley & Sons |doi= 10.1002/9780470771730.ch6|series=PATAI'S Chemistry of Functional Groups}}</ref> It is normally supplied as a 69–70% aqueous solution. Compared to [[hydrogen peroxide]] and organic peracids, ''tert''-butyl hydroperoxide is less reactive and more soluble in organic solvents. Overall, it is renowned for the convenient handling properties of its solutions. Its solutions in organic solvents are highly stable.

==Application==

Industrially, ''tert''-butyl hydroperoxide is used to prepare propylene oxide. In the Halcon process, molybdenum-based catalysts are used for this reaction:

:(CH₃)₃COOH + CH₂=CHCH₃ → (CH₃)₃COH + CH₂OCHCH₃

The byproduct [[t-butanol]] can be dehydrated to [[isobutene]] and converted to [[MTBE]].

On a much smaller scale, ''tert''-butyl hydroperoxide is used to produce some fine chemicals by the [[Sharpless epoxidation]].<ref>[https://www.organic-chemistry.org/chemicals/oxidations/tert-butylhydroperoxide.shtm tert-butyl hydroperoxide at Organic Chemistry Portal]</ref>

== Synthesis and production ==

Many synthetic routes are available,<ref name="Kirk-Othmer">{{cite encyclopedia | title = Peroxides and Peroxide Compounds, Organic Peroxides | encyclopedia = Kirk‑Othmer Encyclopedia of Chemical Technology | author1 = Jose Sanchez | author2 = Terry N.

==Safety==

''tert''-butyl hydroperoxide is potentially dangerous, but explosions are rare.<ref name=Patai/>

A solution of ''tert''-butyl hydroperoxide and water with a concentration of greater than 90% is forbidden to be shipped according to [[US Department of Transportation]] Hazardous Materials Table 49 CFR 172.101.

In some sources it also has an [[NFPA 704]] rating of 4 for health, 4 for flammability, 4 for reactivity and is a potent [[oxidant]],<ref>[http://cameochemicals.noaa.gov/chemical/2692#section1 "TERT-BUTYL HYDROPEROXIDE"] at CAMEO Chemicals NOAA</ref> however other sources claim lower ratings of 3-2-2 or 1-4-4.<ref>[http://chemicalland21.com/specialtychem/perchem/TERT-BUTYL%20HYDROPEROXIDE.htm tert-BUTYL HYDROPEROXIDE] at Chemicalland21</ref><ref>[http://environmentalchemistry.com/yogi/chemicals/cn/tert-Butyl%A0hydroperoxide.html tert-Butyl hydroperoxide] at http://environmentalchemistry.com</ref>
