| Isobutyl propionate Usage And Synthesis |
| Description | Isobutyl propionate has an odor similar to the corresponding ethyl
ester but more refined and fresher. It has a bitter flavor. Prepared
by direct esterification or by reacting propionyl chloride with
isobutyl alcohol in the presence of Mg dust in ether solution. | | Chemical Properties | Isobutyl propionate, has an odor similar to the corresponding ethyl ester, but more refined and fresher. It has a bitter

mushroom, quince, Bourbon vanilla and spineless monkey orange | | Uses | manufacture of fruit essences. | | Preparation | By direct esterification or by reacting propionyl chloride with isobutyl alcohol in the presence of Mg dust in ether solution.
| | Aroma threshold values | Aroma characteristics at 1.0%: fruity, sweet, rummy, pungent, bubble gum estry with a tropical nuance | | Taste threshold values | Taste characteristics at 10 ppm: sweet, fruity, banana, tutti-frutti, with rummy nuances | | General Description | A colorless liquid. Flash point of 86°F. Less dense than water. Vapors heavier than air. May be mildly toxic by ingestion, inhalation and skin absorption. Used to make plastics. | | Air & Water Reactions | Highly flammable. Slightly soluble in water. | | Reactivity Profile | Isobutyl 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. | | Health Hazard | May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | | Safety Profile | Mldly toxic by
ingestion. Flammable when exposed to heat
or flame, can react vigorously with oxidizing
materials. When heated to decomposition it
emits acrid smoke and irritating fumes. See
also ESTERS, PROPIONIC ACID, and
ISOBUTYL ALCOHOL. |
