4-tert-Butylcatechol Usage And Synthesis
  • DescriptionPara-tertiary butyl catechol is specially prepared by reacting the impure catechol fraction with tertiary butyl alcohol. Used for its various properties (inhibition of polymerization and as an antioxidizing agent) in the manufacture of rubber, plastics and paints, in the preparation of petrolatum products, and as an antioxidant in oils, it may induce vitiligo.
  • Chemical Propertieswhite to cream flakes
  • Usesantioxidant in polyester resins; polymerization inhibitor in PVC; antioxidant in oil.
  • UsesPolymerization inhibitor for styrene-butadiene and other olefins.
  • HazardToxic by ingestion and skin absorption.

It may induce vitiligo.
  • Safety ProfileA poison by intravenous route. Moderately toxic by ingestion and skin absorption. A severe skin and eye irritant. Mutation data reported. Combustible when exposed to heat or flame. To fight fire, use Con, dry chemical, fog, mist. When heated to decomposition it emits acrid and irritating fumes
  • Purification MethodsDistil it in a vacuum, then recrystallise it from pentane or pet ether (or *C6H6). [Beilstein
