It is also the most popular pesticide. It is part of entomological stains (the task is to kill insects). Compared to the same chloroform, which is used for a similar purpose, ethyl acetate softens the object of influence more and makes it more pliable in preparation.

This substance is used due to its low toxicity and as a component of fruit essences. This is a well-known food additive E1504. It is added to cooling drinks, liqueurs and various confectionery products. It is used to extract caffeine from coffee.

In laboratory practice, it is used in extraction to pull out the organ. substances from aqueous solutions and chromatography (column and thin layer). Sometimes acts as a solvent in some chemicals. reactions. The rarity of such use is explained by the tendency to solvolysis with water and transesterification.

Pharmacists use it as a reaction medium for the manufacture of a number of drugs: methoxazole, hydrocortisone, rifampicin, etc.

Ethyl acetate is a participant in the synthesis of acetoacetic acid ethyl ester.

When creating explosives, it acts as a gelatinizer. In the electronics industry, when creating aluminum foil and thin sheets of aluminum - as a cleaner and disinfectant. It is also used in the creation of photographs, films, cellophane, and all kinds of technical materials. rubber products.

Ethyl acetate in industry

Or ethanoic acid ester, is widely used in various industries. industries, performing a large list of tasks:

– in paint and varnish, glue, pulp production and the production of artificial leather, ink for typewriters acts as a solvent. The solvent also acts when applying ink drawings and inscriptions to packaging materials;

– in the pharmaceutical industry it serves as a reagent and reaction medium in the manufacture of drugs;

– in the creation of aluminum foil and thin sheets of aluminum – with a degreaser;

– in the electronics industry it is also used for degreasing and also for cleaning;

– in the production of explosives – gelatinizer;

– in the cosmetics industry it is introduced into manicure products, in particular for removing varnish from nails.

This breadth of application is due to the relative low cost, low toxicity and efficiency in each of the above processes.

Due to its high efficiency and functionalism, taking into account its low toxicity, ethyl acetate has become so widely used.

is an ethyl ester of ethanoic acid in the form of a flammable, colorless, volatile liquid substance with a pungent odor of fruit. There are no mechanical impurities. It is a moderately polar solvent product with the properties of esters. Can be dissolved in methyl carbinol, ethyl ether, benzene, methyl trichloride, methylbenzene and some other organic solvents. As for water, the dissolution in it is weaker. It itself has a dissolving effect on cellulose ethers, oil-based resin varnishes, fats and waxes.

Molar mass – 88.11 g/mol, density – 0.902 g/cm³. Thermal properties: melting temperature – -83 °C, boiling temperature – 77 °C. Formula: C 4 H 8 O 2.

Receipt in industry scale occurs during the reaction of ethanol and acetic acid. It is also possible to treat ethanol with carbomethylene or synthesize it from acetaldehyde in the presence of an aluminum alkoxide catalyst.

Applications of ethyl acetate

The main role of this substance is dissolving (this takes up a third of all ethanoic acid ethyl ester produced). It is preferred among other solvents due to its low price, low toxicity and quite tolerable odor. It is used to dissolve nitro- and cellulose acetate, waxes and fats, nitroglyphthalic, perchlorovinyl, epoxy, polyester, silicone varnishes, paints, enamels, and also clean printed circuit boards. Thus, it is used in the production of LC materials, adhesive compositions and inks for printing equipment. When packaging goods using all kinds of flexible packaging materials, it is taken for dissolution during the stencil application of inscriptions and drawings. Together with alcohol, ethyl acetate as a solvent is used, among other things, in the manufacture of artificial leather.

Ethers - organic matter, formed by the interaction of alcohols and acids. Alcohol + acid = ether + water. Ethyl acetate is the result of the esterification of ethyl alcohol and acetic acid. All esters are practically insoluble in water, but interact with water by reacting (hydrolysis of esters is the reverse process of esterification). Ethyl acetate(ethyl acetic acid) is a colorless liquid with a characteristic odor. The literature indicates that ethyl acetate and butyl acetate have a fruity odor. Maybe. But most people who work directly with ethyl acetate are more inclined to think that its smell is reminiscent of acetone, with a slightly sweeter tint. Ethyl acetate is a classic representative of esters (group No. 3 in the classification of solvents for the paint and varnish industry).

As a result, an equilibrium system is formed - on one side there is ether and water, on the other there is alcohol and acid. Although ethyl acetate does not contain water, due to storage conditions (condensation in containers) or in the composition of mixed solvents where water may be present (this is solvent R-646, R-645, R-649, R-650, i.e. practically All solvents that contain alcohols) ethyl acetate, interacting with water, breaks down into its original components - acetic acid and ethyl alcohol. This is why acidity increases over time in solvents containing esters.

Moreover ethyl acetate It mixes better with water than butyl acetate and interacts with it more actively. In the early 90s, some talented chemistry students used ethyl acetate to extract ethyl alcohol. If anyone remembers, it was difficult to find alcohol in stores, and there was a lot of cheap ethyl acetate. Ethyl acetate + water = ethyl alcohol + acid. Neutralize the acid and distill the resulting mixture. Everyone had a good time.

Ethyl acetate mixes well with alcohols, acetone, toluene, orthoxylene, solvent, i.e. with all organic solvents. Dissolves cellulose ethers, oils, fats, chlorinated rubbers, vinyl polymers, carbinol resins, etc. Almost everything is the same as acetone, methyl acetate, butyl acetate. According to dissolving ability ethyl acetate close to acetone, but weaker than it, however, stronger than butyl acetate. Adding a small amount of alcohols enhances the dissolving ability of ethyl acetate.

Raw materials for production. To obtain ethyl acetate, technical acetic acid and ethyl alcohol are used.

Ethyl acetate consumption. Up to 90% of all ethyl acetate produced is consumed by the paint and varnish industry (enamels, paints, varnishes, primers, adhesives, solvents). The remaining volume is used in the production of artificial leather, rubber goods, plastics and pharmaceuticals, cosmetics and the food industry.
