4-tert-Butyltoluene Usage And Synthesis
  • Chemical Propertiescolourless liquid
  • UsesSolvent, intermediate.
  • General DescriptionClear colorless liquid with an aromatic gasoline-like odor.
  • Air & Water ReactionsFlammable. Insoluble in water.
  • Reactivity Profile4-tert-Butyltoluene may react with oxidizing materials.
  • HazardToxic by inhalation, ingestion, and skin absorption. Eye and upper respiratory tract irritant.
  • Fire Hazard4-tert-Butyltoluene is combustible.
  • Safety ProfileModerately toxic by inhalation and ingestion. A skin and human eye irritant. Human systemic effects by inhalation: nausea or vomiting, conjunctiva irritation, unspecified effects on the sense of taste. Inhalation of vapors causes irritation of lungs and depression of central nervous system. Prolonged exposure may result in damage to liver and kidneys. Flammable when exposed to heat or flame. Incompatible with oxidizing materials. When heated to decomposition it emits acrid smoke and fumes.
  • Purification MethodsA sample containing 5% of the meta-isomer is purified by selective mercuration. Fractional distillation of the solid arylmercuric acetate, after removal from the residual hydrocarbon, gives pure p-tert-butyltoluene [Stock & Brown J Am Chem Soc 81 5615 1959].
