Ethyl acetate is removed by the traditional method of sumish distillation. ethyl alcohol, oxtoic and sulfuric acids, as well as by the method of processing ethyl alcohol with ketene, or by the reaction of Tishchenko with acetaldehyde at 0-5 ° C in the presence of catalytic quantities of alcohol to aluminum.

Chemical formula: C4H8O2.

Zastosuvannya ethyl acetate.
As a retailer, being an active retailer of ethylcellulose nitro, it is widely used in the production of lacofarb materials and ink for other machines. It is also included in the compositions of retailers of nitroglyphthalic, perchlorovinyl and epoxy enamels, various oils, waxes, polyester varnishes, farb, organosilicon varnishes and enamels. With this method, up to 30% of the total viroblene ethyl acetate is stained;

Ethyl acetate (ethyl ether optic acid)

ethyl acetate(ethyl ether of octic acid) is a bezbarvna native land with a characteristic odor. The literature suggests that ethyl acetate and butyl acetate can produce a fruity smell. Possibly. But more people, who work without intermediary with ethyl acetate, are more likely to succumb to the smell of nasty acetone, trochs with more licorice. Ethyl acetate is a classic representative of folding ethers (group No. 3 in the classification of retailers for lacofarb industry. Div. division "Products").

Efiri- organic speech, which dissolves with the interaction of alcohols and acids. Alcohol + acid = ether + water. (Report Div. rasdіl "Butyl acetate"). Ethyl acetate is the result of the esterification of ethyl alcohol and octic acid. All ethers are practically indistinguishable from water, but they interact with water, entering into a reaction (hydrolysis of folded ethers is the reverse process of etherification).

As a result, an equally important system is established - from one side ether and water, from the other side alcohol and acid. If you want to take ethyl acetate and do not avenge water, but through the wash water (condensate in containers) or at the warehouse of sumist retailers, you can use water (retailer R-646, R-645, R-649, R-650, so that practically all retailers in such as alcohols) ethyl acetate, interacting with water, breaks down into its own active components - octic acid and ethyl alcohol. The very same among the retailers to the warehouse of which ethers enter, acidity rises from year to year.

And why ethyl acetate In short, lower butyl acetate will go with water and more actively interact with it. On the cob of the 1990s talanovit students-chemists vicorated ethyl acetate for the withdrawal of ethyl alcohol. Just to remember, alcohol in stores was very important, and cheap ethyl acetate was rich. Ethyl acetate + water = ethyl alcohol + acid. Neutralizing acid and overtaking sumish. Usim was good.

ethyl acetate well mixed with alcohols, acetone, toluene, orthoxylene, solvent, to be used by organic retailers. Refining ethers of cellulose, oils, fats, chlorinated rubbers, vinyl polymers, carbinol resins, etc. May everything be the same, like acetone, methyl acetate, butyl acetate. For retail building ethyl acetate close to acetone, weaker to nigo, prote, stronger to butyl acetate. Adding a small amount of spirits - suffice to increase the production of ethyl acetate.

Syrovina for virobnitstva. To remove ethyl acetate, zastosovuyte technical octic acid and ethyl alcohol.

Conservation of ethyl acetate. Up to 90% of all vitrified ethyl acetate is preserved by lacofarb industry (enamels, farby, varnishes, primers, adhesives, retailers). Obsyag, scho zalishivsya, vikoristovuєtsya in the production of piece shkіri, RTI, plastics and pharmaceuticals, cosmetics and food industry.

You can buy ethyl acetate (Ethyl ether of octic acid) at our warehouse, order from metro Podolsk and Klimovsk.

– cetyl ester of ethanoic acid does not have the color of summer and rare speech, which has a sharp smell of fruit. Mechanical houses during the day. Tse in the world is a polar retail product from the power of esters. The distinction is made in methylcarbinol, ethyl ether, benzene, methyltrichloride, methylbenzene and other organic retailers. As far as the driver is concerned, then the difference is weaker. Sam works on ether cellulose, resin varnishes on an oil basis, fats and waxes.

Molar mass - 88.11 g / mol, alkalinity - 0.902 g / cm³. Thermal properties: melting point - -83 °C, boiling point - 77 °C. Formula: C4H8O2.

Removal from prom. scales during the reaction of ethanol optic acid. It is also possible to convert ethanol to help carbomethylene or the synthesis of octal aldehyde for the presence of aluminum alkoxide catalyst.

Ethyl acetate injection

The main role of this speech is rozchinna (on the basis of the tretin of all ethyl ester of etanoic acid, which is released). You are given the honor of the middle of other retailers, through a low price, low toxicity and a generally stern smell. In addition, nitro acetylcellulose, waxes and fats, nitroglyphthalic, perchlorovinyl, epoxy, polyether, organosilicon varnishes, farby, enamels, and also clean other boards. So, the task of preparing LC materials, adhesive compositions and ink for Drukarska technique. When packing goods for additional us_lyaky gnuchkih packing materials, it is necessary to take for rozchinennya pіd an hour of stencil application of writing and malyunkіv. In marriage with alcohol, ethyl acetate is used as a vicorist, moreover, with the preparation of a piece of shkir.

Tse, before that, the most popular otrutochemical. V_n enter to the warehouse of entomological stains (zavdannya - to kill coma). How to respect for yourself chloroform, which zastosovuєtsya with a similar method, ethyl acetate is more rozm'yakshuє ob'єkt infusion and rob it more pliable in preparation.

The speech is given through low toxicity and as a warehouse of fruit essences. The price is an additive up to їzhi E1504. Bring in cold drinks, liqueurs and confectionery. To help you extract the caffeine.

In laboratory practice, it is necessary to know the need for extraction for organ vitiation. speeches from water varieties and chromatography (column and fine ball). Sometimes you act as a retailer at the deiky chemists. reactions. The rіdkіsnіst іn such vikoristannya is explained by schilnіstі to solvolіzі water іn transterfіkatsії.

Pharmacists zastosovuyt yoga as a reaction medium for the preparation of low drugs: metoxazole, hydrocortisone, rifampicin and other.

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

Under the hour of the creation of the vibukhivka, the gelatinizer acts. In an electronic window, when folding aluminum foil and thin sheets of aluminum - with a cleaner and non-infectious. Zadіyuєtsya and creation of photo-film, cellophane, all those. virobiv z gumi .

Ethyl acetate in industry

ethyl acetate, or the ether of ethanoic acid, to know a wide variety of industrial applications. galuzy, vykonuyuchi great perelіk zavdan:

- in lakofarbovym, glue, cellulose brewing and prepared piece sheets, ink for drukar typewriters is performed by a retailer. Also, the retailer does when applying ink small patches and writing on packing materials;

– in the pharmaceutical industry, serve as a reagent and a reaction medium in the preparation of liquids;

- in case of folding aluminum foil and thin sheets of aluminum - anti-grease;

- in electronic industry, it is also victorious for fat loss, as well as cleansing;

- A popular extractant in the food industry (for example, it helps to extract caffeine from caviar). In addition, it’s hot when you mix cold drinks, liqueurs, confectionery and fruit essences;

– in virobnitstvі vibukhіvki – gelatinizator;

- in the cosmetic industry, add to the warehouse supplies for manicure, zocrema, for removing lacquer coating from nails.

This latitude of zastosuvannya is conditioned by a good low-cost, low-toxicity and efficiency in skin resurfacing processes.
