ISOPROPYL PROPIONATE Usage And Synthesis

Description

Isopropyl propionate has a bittersweet taste reminiscent of plum. May be synthesized by direct esterification in benzene solution and in the presence of p-toluenesulfonic acid.

Chemical Properties

Isopropyl propionate has a bittersweet taste reminiscent of plum.

Occurrence

Reported found in raspberry, currant, kumquat peel oil, papaya and plum brandy

Definition

ChEBI: Isopropyl propionate is an isopropyl ester. It is functionally related to a propionic acid.

Preparation

By direct esterification in benzene solution and in the presence of p-toluenesulfonic acid

Taste threshold values

Taste characteristics at 20 ppm: fruity, berry with a slight bubble gum nuance

General Description

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.

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

ISOPROPYL 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.
