Methyl butyrate Chemical Properties,Uses,Production


Metyhl butyrate occurs naturally in apples, apricot, blackberry, nectarine etc. It is used as a flavor ingredient in fruit and rum flavoring for beverages, ice cream, candy, and baked goods. Methyl butyrate is also used to synthesize butyraldehyde.

Methyl butyrate, also known under the systematic name methyl butanoate , is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer. Although it is flammable, it has a relatively low vapor pressure ( 40 mm Hg at 30 °C ), so it can be safely handled at room temperature without special safety precautions.
Methyl butyrate is present in small amounts in several plant products, especially pineapple oil. It can be produced by distillation from essential oils of vegetable origin, but is also manufactured on a small scale for use in perfumes and as a food flavoring.
Methyl butyrate has been used in combustion studies as a surrogate fuel for the larger fatty acid methyl esters found in biodiesel. However , studies have shown that, due to its short-chain length, methyl butyrate does not reproduce well the negative temperature coefficient (NTC) behaviour and early CO2 formation characteristics of real biodiesel fuels. Therefore, methyl butyrate is not a suitable surrogate fuel for biodiesel combustion studies.

Chemical Properties

Methyl butyrate has an apple-like odor and a corresponding sweet taste that is not very powerful. Below 100 ppm, it may have a banana-pineapple flavor. May be prepared from methyl alcohol and butyric acid in the presence of concentrated H2S04.

manufacture of artificial rum and fruit essences.


Methyl butyrate is used as a solvent for ethylcellulose and nitrocellulose resins. It is also used in lacquers and perfumes and in the manufacture of rum and fruit flavors.


From methyl alcohol and butyric acid in the presence of concentrated H2SO4.

Production Methods

Methyl butyrate is produced from methyl alcohol and butyric acid in the presence of concentrated sulfuric acid .

Production Methods

Methyl butyrate is produced from methyl alcohol and butyric acid in the presence of concentrated sulfuric acid.

Aroma threshold values

Detection: 1 to 43 ppb. Aroma characteristics at 1.0%: pungent, ethereal, fruity, fumey and fusel with a fermented, cultured, creamy undernote.

Taste threshold values

Taste characteristics at 10 ppm: fruity and apple-like with a sweet almost buttery, nutty and creamy nuance, fusel-like, impacting, and estry with a cultured dairy, acidic depth.

General Description

A clear colorless liquid. Flash point 57°F. Less dense than water and slightly soluble in water. Hence floats on water. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

Methyl butyrate reacts exothermically with acids to generate alcohols and carboxylic acids. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with basic or caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides .


Flammable, dangerous fire risk.

Health Hazard

Irritating to the eyes, nose, throat, upper respiratory tract, and skin.

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.

Safety Profile

Moderately toxic by ingestion and skin contact. A skin irritant. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. Can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.


Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.

Purification Methods

Treat the ester with anhydrous CuSO4, then distil it under dry nitrogen. [Beilstein 2 IV 786.]
