Ethyl acetate formula

The chemical formula for ethyl acetate is CH3COOCH2CH3.  

The formula for ethyl acetate, as well as its structure, is provided here. Ethyl acetate, also known as ethyl ethanoate, is an organic compound that is most commonly used as an intermediary in a variety of chemical reactions. Ethyl acetate is produced by the direct esterification of ethyl alcohol with acetic acid, which is accomplished by mixing acetic acid with an excess of ethyl alcohol and adding a small amount of sulphuric acid to the mixture.

Ethyl ethanoate is commonly referred to by the abbreviations EtOAc, EA, or ETAC. It has a molar mass of 88.106 g/mole and is a halogen. It has a sp2 hybridization in the carbonyl group, and the other part of the molecule is made up of a tetrahedral geometry on the other side. The structural formula of ethyl acetate, are provided below.

Production and synthesis:

When the Count de Lauraguais first discovered ethanol acetate, it was by distilling a mixture of ethanol and acetic acid in 1759 that the scientific community took notice.  

In 2004, approximately 1.3 million tonnes were produced worldwide, according to estimates.

 In 1985, the combined annual production of Japan, North America, and Europe amounted to approximately 400,000 tonnes. The global ethyl acetate market was worth $3.3 billion in 2018, according to industry estimates. 

Ethyl acetate is primarily produced in industry through the Fischer esterification reaction, which involves the reaction of ethanol and acetic acid. At room temperature, this mixture converts to the ester in a yield of approximately 65 percent:

In the reaction:

CH3COOH + CH3CH2OH – CH3CO2CH2CH3 + H2 

Acid catalysis can be used to speed up the reaction, and the equilibrium can be shifted to the right by removing water from the equation. 

It is also prepared in industry by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst, which is accomplished through the Tishchenko reaction:

     2 CH3CHO – CH3CO2CH2CH3

 Silicotungstic acid is used in the production of ethyl acetate, which is produced through the alkylation of acetic acid by ethylene: 

        C2H4 + CH3CO2H – CH3CO2C2H5 

Ethyl acetate uses:

It is primarily used as a solvent and diluent, and is preferred because of its low cost, low toxicity, and pleasant odour. It is also used as a solvent and diluent in the pharmaceutical industry. [a citation is required] For example, it is commonly used to clean circuit boards and is also found in some nail varnish removers, among other applications (acetone is also used). With the help of this solvent, coffee beans and tea leaves are decaffeinated (when supercritical CO2 extraction is not possible). It is also used in paints as an activator or hardener, as well as in other products. Ethyl acetate can be found in a variety of products, including confectionery, perfumes, and fruits. When used in perfumes, it evaporates quickly, leaving the perfume’s scent on the skin for a short time. 

Laboratory uses: In the laboratory, ethyl acetate mixtures are frequently used in column chromatography and extractions, among other applications. It is uncommon to use ethyl acetate as a reaction solvent because it is susceptible to reactions such as hydrolysis, transesterification, and condensation. 

Occurrence in wine: Ethyl acetate is the most common ester in wine, and it is formed during the fermentation process as a result of the reaction between the most common volatile organic acid – acetic acid – and the ethyl alcohol produced. When ethyl acetate is present, the aroma is most noticeable in younger wines, and it contributes to the overall perception of “fruitiness” in the wine. The perception threshold varies from person to person, with the majority of people having a threshold around 120 mg/L. An excessive amount of ethyl acetate is considered a flaw in a wine’s production.

Safety precautions:

Ethyl acetate is a highly effective entomological asphyxiant that can be used in the collection and study of insects, among other things. The vapours from an ethyl acetate-charged killing jar will quickly kill the insect that has been collected without causing it any damage. It also helps to keep the insect soft enough to allow for proper mounting suitable for inclusion in an insect collection because it is not hygroscopic.

Eye, nose, and throat irritation are possible as a result of excessive exposure to ethyl acetate (EA). Overexposure to high levels of radiation can result in weakness, drowsiness, and unconsciousness. Ethyl acetate is an irritant to the conjunctiva and mucous membranes of the respiratory tract that should be avoided if possible. Several animal studies have demonstrated that the ester has depressant and lethal effects at very high concentrations; at concentrations ranging from 20,000 to 43,000 ppm (2.0–4.3 percent), pulmonary edema with haemorrhages, signs and symptoms of central nervous system depression, secondary anaemia, and liver damage have been observed. In humans, concentrations as low as 400 parts per million (ppm) cause irritation of the nose and pharynx; cases of irritation of the conjunctiva with temporary opacity of the cornea have also been reported. Skin eruptions and sensitization of the nasal mucous membrane have been reported in rare cases following exposure. Its irritant effect is weaker than that of propyl acetate or butyl acetate, and it is less irritating than that of acetic acid.
