APPLICATIONS

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.
Methyl butyrate, one of the odorous compound present in different types of adhesive (hotmelt, vinyl acetate ethylene, starch, polyvinyl acetate and acrylic) used in food packaging, was identified by GC-O-MS (gas chromatography–mass spectrometry–olfactometry).

Methyl Butyrate has been used in combustion studies as a surrogate fuel for the large fatty acid methyl esters in biodiesel.
Methyl butyrate is used as a solvent for ethylcellulose and nitrocellulose resins. 
Also, Methyl butyrate is used in lacquers and perfumes and in the manufacture of rum and fruit flavors.

Methyl butyrate is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields.
Methyl butyrate is used in manufacture of artificial rum and fruit essences.

DESCRIPTION

Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. 
Like most esters, Methyl butyrate has a fruity odor, in this case resembling apples or pineapples.
At room temperature, Methyl butyrate is a colorless liquid with low solubility in water, upon which it floats to form an oily layer. 
Although Methyl butyrate is flammable, Methyl butyrate has a relatively low vapor pressure (40 mmHg at 30 °C (86 °F)), so Methyl butyrate 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.
Methyl butyrate 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.

Methyl butyrate appears as a clear colorless liquid. 
Flash point of Methyl butyrate is 57°F. 
Methyl butyrate is Less dense than water and slightly soluble in water. 
Hence Methyl butyrate floats on water. 
Vapor of Methyl butyrate is heavier than air.

Methyl butyrate is a fatty acid ester.
Methyl butyrate is a natural product found in Ananas comosus, Carica papaya, and other organisms with data available.

Methyl butyrate belongs to the class of organic compounds known as organic acid methyl esters. 
Organic acid methyl esters are compounds containing an organic acid that is esterified with a methyl group. 
They have the general structure RC(=O)OR', where R= aliphatic tail or organyl group and R'=methyl group. 
Methyl butyrate is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.

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