| Hazard Information | Back Directory | [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.
| [Description]
Tert-Butyl peroxybenzoate (TBPB) is an organic compound with the formula C6H5CO3CMe3 (Me = CH3). TBPB, a pale yellow, is exclusively encountered as a solution in solvents such as ethanol or phthalate. It is an ester of peroxybenzoic acid and the most widely produced perester. | [Chemical Properties]
colourless or slightly yellow liquid | [Synthesis Reference(s)]
Journal of the American Chemical Society, 68, p. 642, 1946 DOI: 10.1021/ja01208a033 | [Health Hazard]
t-Butyl peroxybenzoate is a mild skin andeye irritant. Exposure to 500 mg/day causedmild irritation in rabbit eyes and skin. Toxicitydata on animals show a low order oftoxicity.
LD50 value, oral (mice): 914 mg/kg
It has been reported to cause tumors(blood) in mice. Its carcinogenic actions onhumans are unknown. | [Fire Hazard]
Highly reactive and oxidizing compound
with moderate flammability; flash point (open
cup) 107–110°C (224.6–230°F); autoignition
temperature not reported.
It forms an explosive mixture with air; the
explosive range not reported. It is not sensitive
to shock but is heat sensitive. It explodes
on heating; self-accelerating decomposition
temperature 60°C (140°F).
It may react explosively when mixed with
readily oxidizable, organic, and flammable
substances. Fire-extinguishing agent: water
from a sprinkler; use water to keep the
containers cool. | [Flammability and Explosibility]
Flammable(100%) | [Carcinogenicity]
Other studies have determined
the possibility that t-butyl peroxybenzoate can be metabolized
to free radicals by human carcinoma skin keratinocytes.
Free radicals are suggested to be involved in the cascade of
events occurring during tumor promotion . | [storage]
It should be stored in a well-ventilatedplace at a temperature between 10 and27°C (50–80°F), isolated from oxidizable,flammable, organic materials and accelerators.It should be shipped in glass, polyethylene,and earthenware containers of up to5-gallon capacity placed inside wooden orfiberboard boxes. |
