Safety Profile
Moderately toxic by ingestion. A skin and eye irritant. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. See also PEROXIDES, ORGANIC. Potentially explosive when heated above 11 5'C. Explosive reaction on contact with organic matter or copperQ) bromide + limonene. When heated to decomposition it emits acrid smoke and fumes.

Hazard Information

General Description
Clear, colorless to slightly yellow liquid with a mild, aromatic odor. TERT-BUTYL PEROXYBENZOATE, [<= 75% IN SOLUTION] also is stored and transported as a mixture with inert solids and as a solvent slurry, to mitigate the explosion hazard.
Reactivity Profile
TERT-BUTYL PEROXYBENZOATE explodes with great violence when rapidly heated to a critical temperature; pure form is shock sensitive and detonable [Bretherick 1979 p. 602]. Upon contact with organic matter, t-butyl peroxybenzoate can ignite or give rise to an explosion [Haz. Chem. Data 1973 p. 77].
Air & Water Reactions
Insoluble in water.
Hazard
Oxidizing material; do not store near com- bustible materials.
