Isopropyl butyrate has a pleasant odor reminiscent of butyric acid.
May be synthesized from butyric acid and propylene in presence
of concentrated H2S04 at 125°C in sealed tube; also from butyric
acid and isopropyl alcohol in the presence of HCL or p-toluenesulfonic acid.
Isopropyl butyrate has a pleasant odor reminiscent of butyric acid.
Reported found in strawberry, cranberry, kumquat peel oil, apricot, papaya, blue cheeses, sparkling wine, passion fruit and spineless monkey orange
Isopropyl butyrate was used as intravaginal taggant in the study of "breath test" for vaginal gel use.
Solvent for cellulose ethers, flavoring.
ChEBI: Isopropyl butyrate is a fatty acid ester and an isopropyl ester.
From butyric acid and propylene in presence of concentrated H2SO4 at 125°C in sealed tube; also from butyric acid and
isopropyl alcohol in the presence of HCl or p-toluenesulfonic acid
Taste characteristics at 30 ppm: sweet, fruity, estry, green and ripe
A colorless liquid. Flash point near 30°F. Boiling point near 280°F. Less dense than water. Vapors heavier than air. Used as a solvent and to make flavorings.
Highly flammable. Soluble in water.
ISOPROPYL BUTYRATE 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.
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.
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.
