Tert- butyl hydroperoxide (TBHP ) is an organic chemical compound belonging to the group of hydroperoxides and occurs in the form of a colorless, pungent smelling liquid. TBHP is the simplest tertiary hydroperoxide.

Production and representation

Tert-butyl hydroperoxide can be obtained by reaction of tert-butyl alcohol with hydrogen peroxide in an acidic solution ( sulfuric acid).

Properties

Tert- butyl hydroperoxide is a colorless, flammable, liquid with a pungent odor. TBHP is continue to a strong oxidizing agent.

Use

As the organic peroxide tert- butyl hydroperoxide finds many uses. It can be used as:

• As a starter (initiators ) for the radical polymerization - mass production of plastics materials
• For networking and modification of plastics
• For the curing of unsaturated polyester resins
• As a disinfectant - eg peroxyacetic acid formulations in food technology
• As an oxidizing agent (for example, phenols and peroxide )
• In waste water treatment
• In the Sharpless epoxidation ( epoxidation of allylic alcohols, primary or secondary )
• The Halcon process for the preparation of organic compounds (e.g. propylene oxide, ethylene glycol ).

Safety

Vapors of tert-butyl hydroperoxide may form explosive mixtures with air at temperatures above the flash point (26 ° C). tert-butyl hydroperoxide is the only material that transmits the maximum value of 4 in the NFPA -704 system in all three categories.
