tert-Butyl peroxyacetate

Other Classes -> Peroxides, Organic

Flammable agents - 3rd degree

This liquid peroxide is sensitive to heat. Storage of this material must be done so with stringent temperature control measures. Its explosion hazard is also mitigated by mixing the peroxide with an inert solid.

Ethaneperoxoic acid, 1,1-dimethylethyl ester: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.

The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

A strong oxidizer that may cause fire or explosion on contact with combustible materials; Explosive and sensitive to heat and shock; [CAMEO] A moderate eye irritant; Causes respiratory depression, GI bleeding, abnormal liver function results, and effects on spermatogenesis in acute inhalation studies (species not specified); Causes abnormal recording from peripheral motor nerves, proteinuria, hemolysis, and effects on spermatogenesis and male reproductive organs in acute inhalation studies of rats; [RTECS] Solution in 10-30% aliphatic hydrocarbons (Stoddard type, CAS# 8052-41-3): Organic peroxide that may cause fire or explode on heating; A skin and strong eye irritant; Harmful by ingestion; Possible carcinogen and mutagen; [Sigma-Aldrich MSDS] See Peroxybenzoic acid, t-butyl ester and Diisopropyl peroxydicarbonate.

TERT-BUTYL PEROXYACETATE 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 peroxyacetate can ignite or give rise to an explosion [Haz. Chem. Data 1973 p. 77].
