Ethyl butyrate Usage And Synthesis


Description

Ethyl butyrate is an ester soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple. Ethyl butyrate is present in many fruits e.g. apple, apricot, banana, plum, tangerine etc.
Ethyl butyrate is used as an artificial flavoring resembling orange juice or pineapple in alcoholic beverages, as an ingredient of fragrance, and as a solvent and plasticizer for cellulose. It is also used in the production of polyvinyl butyral (PVB).

Uses

Ethyl Butyrate is used in flavorings, extracts, perfumery, and as a solvent. These are not necessarily FDA approved indications, but instead are uses of liquid nitrogen.It is synthesized by reacting ethanol and butyric acid in a condensation reaction.
Ethyl Butyrate is perceived as a tropical fruit, tutti fruity, mango or pineapple flavour. One of the ester flavours found in most beers, it can also be perceived as a slightly cheesy fruit flavour. Ethyl Butyrate generally occurs in beers due to fermentation and too much is normally considered an off flavour.
Applications: artificial flavoring resembling orange juice or pineapple in alcoholic beverages, as a solvent in perfumes, and as a plasticizer for cellulose.

Chemical Properties

Ethyl Butyrate occurs in fruits and alcoholic beverages, but also in other foods such as cheese. It has a fruity odor, reminiscent of pineapples. Large amounts are used in perfume and in flavor compositions.

Chemical Properties

Ethyl butyrate is a colorless liquid. Pineapple odor. The Odor Threshold is 0.015 ppm.

Chemical Properties

colourless liquid with a fruity odour

Chemical Properties

Ethyl butyrate has a fruity odor with pineapple undertone and sweet, analogous taste.

Uses

manufacture of artificial rum; perfumery; the alcoholic solution constitutes the so-called "pineapple oil".

Production Methods

Ethyl Butyrate can be synthesized by reacting ethanol and butyric acid. This is a condensation reaction, meaning water is produced in the reaction as a byproduct.

Preparation

By esterification of n-butyric acid with ethyl alcohol in the presence of Twichell’s reagent or MgCI2; also by heating n-butyl alcohol and ethanol over CuO + UO3 catalyst at 270°C
