tert-Butyl peroxyacetate Usage And Synthesis
  • Chemical Propertiesclear solution
  • UsesPolymerization initiator for vinyl monomers, manufacture of polyethylene and polystyrene.
  • UsesIt is used to initiate polymerization, and inorganic syntheses.
  • General Descriptiontert-Butyl peroxyacetate is sensitive to heat. Storage of tert-Butyl peroxyacetate must be done so with stringent temperature control measures. It's explosion hazard is also mitigated by mixing the peroxide with an inert solid.
  • Reactivity Profiletert-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].
  • HazardFlammable, dangerous fire risk. Oxidizer.
  • Health HazardMild skin and eye irritant. Its toxicity is low,both via inhalation and ingestion routes.
    LD50 value, oral (rats): 675 mg/kg.
  • Fire HazardThe pure compound is highly reactive and oxidizing, and sensitive to heat and shock.
    A 75% solution in benzene or mineral spirits is the maximum assay that is sold commercially. Its benzene solution at this concentration is reactive, oxidizing, and flammable. The flash point varies depending on the solvent; the autoignition temperature not reported; the self-accelerating decomposition temperature is 93°C (199.4°F).
    t-Butyl peroxyacetate forms an explosive mixture with air, explosive range not reported. It can ignite or explode when in contact with combustible organic compounds. Fire-extinguishing agent: water from a sprinkler from an explosion-resistant location; keep the containers cool.
  • Safety ProfileModerately toxic by ingestion. Mildly toxic by inhalation. Moderate skin and eye irritant. A shockand heat-sensitive explosive. Dangerous fire hazard when exposed to heat, flame, reducing agents. To fight fire, use dry chemical, alcohol foam, spray and mist. When heated to decomposition it emits acrid smoke and fumes.

  • storageStore in a cool and well-ventilated placeisolated from other chemicals; protect fromphysical damage. It is shipped in glass andearthenware containers not exceeding 7 lb,inside a wooden or fiberboard box.
  • Purification MethodsWash the ester with NaHCO3 from a *benzene solution, then redistil to remove *benzene [Kochi J Am Chem Soc 84 774 1962]. Handle with adequate protection due to possible EXPLOSIVE nature. [Beilstein 2 IV 391.]
