Hazards and Toxicity
UCAR n-Butyl Propionate may irritate skin and eyes.
Exposure to its vapor may cause eye and respiratory system irritation.
Upon ingestion, causes abdominal pain and nausea.
UCAR n-Butyl Propionate is very flammable.
UCAR n-Butyl Propionate may ignite even at ambient temperatures.
Above 32 °C (90 °F), explosive mixtures with air may be formed.
Strong oxidizing acids may cause a violent reaction that is sufficiently exothermic to ignite UCAR n-Butyl Propionate and the reaction products.
Upon catching a fire, irritating, toxic and suffocating gases may be produced, such as carbon dioxide and carbon monoxide.

Reactivity Profile
UCAR n-Butyl Propionate 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.
