Glossary - Butyl Acetate

A clear colourless liquid with a fruity odour and a flash point of 72 - 88°F.  A density of 7.4 lb / gal floats on water.

  • vapours heavier than air
  • highly flammable
  • very slightly soluble in water

Butyl acetate is an ester.  Esters react with acids to liberate heat along with alcohols and acids.  Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.

Heat is also generated by the interaction of esters with caustic solutions.  Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.  Attacks many plastics.


  • SKIN: Prolonged or frequently repeated exposures may lead to drying.
  • INHALATION: Headaches, dizziness, nausea, irritation of respiratory passages and eyes.
  • HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.  Vapours may form explosive mixtures with air.  Vapours may travel to source of ignition and flash back.  Most vapours are heavier than air.  They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapour explosion hazard indoors, outdoors or in sewers.  Runoff to sewer may create fire or explosion hazard.  Containers may explode when heated.
