Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odour, in this case resembling apples or pineapples. At room temperature, it is a colourless liquid with low solubility in water, upon which it floats to form an oily layer. Although it is flammable, it has a relatively low vapour pressure (40mm Hg at 30OC), so it can be safely handled at room temperature without special safety precautions.[2]
It is present in small amounts in several plant products, especially pineapple oil.[3] It can be produced by distillation from essential oils of vegetable origin, but is also manufactured on a small scale for use in perfumes[4] and as a food flavouring.
Methyl butanoate has been used in combustion studies as a surrogate fuel for the larger fatty acid methyl esters found in biodiesel.[5] However, studies have shown that, due to its short-chain length, methyl butanoate does not reproduce well the negative temperature coefficient (NTC) behaviour and early CO2 formation characteristics of real biodiesel fuels. Therefore, methyl butanoate is not a suitable surrogate fuel for biodiesel combustion studies.[6]
