2-Ethylbutyl acetate Usage And Synthesis

Chemical Properties

Clear colorless liquid, Sp.Gr. 0.88. B.P. 163°C. 0.06 % soluble in water, soluble in alcohol, miscible with oils.
Fruity, somewhat oily odor of rather nondescript type. Sweet-fruity taste, reminiscent of Pear and Strawberry.

Uses

Solvent for nitrocellulose lacquers, flavoring.
2-Ethylbutyl acetate is comparatively stable against hydrolysis, and finds therefore some use in soap Perfumery to lend fruity notes and lift to the ponion of the composition. It blends well with aldehydic and rosy fragrance types, and supports Geranium, Lavender or minty notes excellently.
Traces of the ester arc occasionally used in flavor compositions for fruit complexes, etc. Usually about 5 to 8 ppm in the finished product.

Preparation

By reacting 2-ethylbutanol with acetic anhydride or acetic acid in the presence of sulfuric acid.

Definition

ChEBI: 2-Ethylbutyl acetate is a carboxylic ester.

General Description

A clear colorless liquid. Flash point 130°F. Denser than water and insoluble in water. Vapors heavier than air.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

2-Ethylbutyl 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.

Hazard

Moderate fire risk.

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.
