Incompatibilities
Vapor may form explosive mixture with
air. Reaction, possibly violent, on contact with oxidizers.
Compounds of the carboxyl group react with all bases, both
inorganic and organic (i.e., amines) releasing substantial
heat, water and a salt that may be harmful. Incompatible
with arsenic compounds (releases hydrogen cyanide gas),
diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing
hydrogen sulfate and oxides of sulfur)

Chemical Properties
Butyl Isovalerate is a clear liquid.
Waste Disposal
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed.
Occurrence
Reported found in the oil from leaves of Eriostemon coxii and Phebalium dentatum; also in apricot, banana,
cheeses, olive and plum.
Uses
Butyl isovalerate is occasionally used in flavor compositions,
mainly in Chocolate flavors and fantasy fruit
or Tutti-frutti, etc. Concentrations are normally about 50 ppm
in the finished product.
Definition

Preparation
By prolonged boiling of the acid with n-butyl alcohol in benzene in the presence of concentrated H2SO4.
Taste threshold values
Taste characteristics at 5 ppm: fruity, sweet, pineapple, ripe, musty and green with a slight cheesy nuance.
storage
Color Code—Red: Flammability Hazard: Store in aflammable liquid storage area or approved cabinet away fromButyl isovalerate 479ignition sources and corrosive and reactive materials. Prior toworking with this chemical you should be trained on itsproper handling and storage. Before entering confined spacewhere butyl isovalerate may be present, check to make surethat an explosive concentration does not exist. Store in tightlyclosed containers in a cool, well-ventilated area. Metal containers involving the transfer of this chemical should begrounded and bonded. Where possible, automatically pumpliquid from drums or other storage containers to process containers. Drums must be equipped with self-closing valves,pressure vacuum bungs, and flame arresters. Use only nonsparking tools and equipment, especially when opening andclosing containers of this chemical. Sources of ignition, suchas smoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create apotential fire or explosion hazard
