General Description
A water-white liquid with an apple-like odor. Less dense than water. Flash point 90°F. May irritate skin and eyes. Used to make perfumes and flavorings.
Reactivity Profile
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.
Air & Water Reactions
Highly flammable. Very slightly soluble in water.
Hazard
Skin and eye irritant. Flammable, moderate
fire risk.
Health Hazard
Contact will cause eye and skin irritation. Vapor exposure may cause eye and respiratory tract irritation.
Potential Exposure
It is used as a solvent or lacquer thinner; and in perfumes and flavoring
Fire Hazard
Special Hazards of Combustion Products: Irritating and toxic gases, such as carbon dioxide and carbon monoxide, may be produced in fire.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Shipping
UN1914 Butyl propionates, Hazard Class: 3;
Labels: 3—Flammable liquid
Incompatibilities
Vapor may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides. May accumulate static electrical
charges and cause ignition of its vapors.

Definition
ChEBI: Butyl propionate is a propanoate ester of butan-1-ol. It has a role as a plant metabolite, a human metabolite, an insect attractant and a flavouring agent. It is functionally related to a butan-1-ol.
Preparation
By esterification of propionic acid with n-butyl alcohol in the presence of concentrated H2SO4 or p-toluene sulfonic acid.
Aroma threshold values
Detection: 25 to 440 ppb
Flammability and Explosibility
Flammable
storage
Color Code—Red: Flammability Hazard: Storein a flammable liquid storage area or approved cabinetaway from ignition sources and corrosive and reactivematerials. Protect against physical damage. Outside ordetached storage is preferred. Prior to working with butylpropionate you should be trained on its proper handlingand storage. Store in tightly closed containers in a cool,well-ventilated area away from incompatible materialslisted above. Metal containers involving the transfer ofthis chemical should be grounded and bonded. Drumsmust be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only nonsparkingtools and equipment, especially when opening and closingcontainers of this chemical. Sources of ignition, such assmoking and open flames, are prohibited where this chemical is used, handled, or stored in a manner that could create a potential fire or explosion hazard
Toxics Screening Level
The initial threshold screening level (ITSL) for n-butyl propionate is 102 μg/m3 (annual averaging time).
