Methyl hexanoate Usage And Synthesis

Description

Methyl hexanoate is the methyl ester form of hexanoate with fruity type odor and flavor. It is formed by the esterification between methanol and hexanoate. It can be found in many sources such as wine grapes, melon, raspberry, blackberry, plum, quince, apple brandy, wines, Bourbon vanilla, coffee, black tea, potato, tomato, cheeses, rye bread, meats and other foodstuffs. Its major application is used as cosmetic, flavor and fragrance agents.

Description

Methyl hexanoate has an ether-like odor reminiscent of pineapple. May be prepared by reacting methyl alcohol with hexanoic acid at 130 - 140°C in the presence of concentrated H2S04 and distilling the ester from the reaction mixture.

General Description

Clear colorless liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Methyl hexanoate 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. Methyl hexanoate reacts with strong oxidizing agents and strong bases.

Fire Hazard

Methyl hexanoate is combustible.

Flammability and Explosibility

Flammable

Synthesis

Methyl caproate is synthesized by direct esterification of n-Caproic (n-Hexanoic) acid with Methanol, preferably under azeotropic conditions.

Purification Methods

Pass it through alumina and distil it before use. [Beilstein 2 IV 921.]
