Typical Properties
Summary
Tert butyl hydrogen peroxide (TBHP) is one of the most commonly used alkyl hydroperoxides. Commodities are generally light yellow transparent nonvolatile liquid, slightly soluble in water and miscible with organic solvents. Butyl hydrogen peroxide is mainly used as initiator for free radical reaction or polymerization in industry. Compared with most other initiators, the decomposition products of TBHP are acidic. The decomposition products of TBHP are tert butyl alcohol (TBA) and a small amount of acetone, which has no corrosion to the equipment, so the requirements for the device are not high.
