Miris

Its odour is described as fruity, juicy fruit, pineapple, cognac, sweet and tutti frutti. The odour is pineapple with a banana note, sweet, juicy and tutti-frutti in character. Its odor strength is very high, powerful and extremely diffusive.

Detaljno

Ethyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of ethanol with the carboxy group of butyric acid. It appears as a clear colorless liquid with a pineapple-like odor. It also occurs naturally in many fruits, albeit at lower concentrations.

Occurrence

Ethyl n-butyrate, present at 0.033 ppm, is a volatile flavor component of fresh grapefruit juice. It is present in pineapple guava at 0.31 ug/kg of fruit. In Japanese muskmelon it was detected, contributing a grape-like odor.

Chemistry and properties

Ethyl butyrate is soluble in propylene glycol, paraffin oil, and kerosene. Its vapors are heavier than air. It may attack some forms of plastics. Ethyl butyrate from natural sources can be told apart from the synthetic material by stable isotope ratio analysis.

Other uses

Ethyl butyrate is used in manufacturing artificial rum. Its alcoholic solution constitutes the so-called "pineapple oil". It is also used as a plasticizer for cellulose and in a solvent mixture for cellulose esters and ethers.

Zanimljivosti

In industrial use, ethyl butyrate is one of the cheapest chemicals. It is used in nearly all orange juices sold in the US, including those sold as "fresh" or "concentrated".

Dobijanje i hemija

Način dobijanja

It can be synthesized by reacting ethanol and butyric acid. This is a condensation reaction, meaning water is produced in the reaction as a byproduct. Ethyl butyrate is synthesised in Jamaican rum upon the esterification of butyric acid from muck and ethanol during the distillation process.
