Chemical Properties

colourless liquid


As polymerization catalyst.

General Description

Clear colorless liquid.

Reactivity Profile

The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Di-tert-butyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 1979v.

Purification Methods

Wash the peroxide with aqueous AgNO3 to remove olefinic impurities, water and dry (MgSO4). Free it from tert-butyl hydroperoxide by passage through an alumina column [Jackson et al. J Am Chem Soc 107 208 1985], and if necessary two high vacuum distillations from room temperature to a liquid-air trap [Offenbach & Tobolsky J Am Chem Soc 79 278 1957]. [Beilstein 1 IV 1619.] The necessary protection from EXPLOSION should be used.
