Excellent Industrial Solvent Ethyl Acetate CAS 141-78-6 C4H8O2

Ethyl acetate product basic information

Ethyl acetate (EA), also known as ethyl acetate, has a chemical formula of C4H8O2 and is an organic compound.

Synonyms: ETAC, acetic ester, Ethyl acetate, SPIRIT OF WINE, METHYLCARBINOL, REAGENT ALCOHOL, Acetic acid ethyl ester, METHYLATED SPIRIT INDUSTRIAL, METHYLATED SPIRIT MINERALISED

Ethyl acetate appears as a colorless liquid with a fruity aroma, is soluble in most organic solvents, and is slightly soluble in water. Ethyl acetate is flammable, volatile, and low-toxic. It is an important organic chemical raw material and industrial solvent.

Ethyl acetate production process

The production processes of ethyl acetate include ethanol dehydrogenation, acetate esterification, acetic acid/ethylene addition and acetaldehyde condensation. The acetate esterification method is the mainstream preparation method of ethyl acetate in my country, accounting for 95.0% of the production capacity. The acetate esterification method refers to the esterification reaction of ethanol and acetic acid under the action of a catalyst to finally produce ethyl acetate. However, at present, the acetate esterification method has shortcomings such as high production costs, easy environmental pollution, and easy equipment corrosion, and is gradually being replaced by new green and energy-saving processes such as the salting out method.

Ethyl acetate uses

Ethyl acetate is a widely used fine chemical product with excellent solubility, quick drying and fruity aroma. Ethyl acetate has a wide range of uses. It is a very important organic chemical raw material and an excellent industrial solvent. It is widely used in acetate fiber, ethyl fiber, chlorinated rubber, vinyl resin, acetate fiber resin, synthetic rubber, coatings and During the production process of paint, etc. The main usage proportions are: packaging and printing (50%), adhesives (20%), industrial alcohol (7%), medicine (16%), and others (7%).

• Ethyl acetate has excellent solubility, can be dissolved in most organic solvents, and is slightly soluble in water. Based on this property, ethyl acetate is used as an industrial solvent:

1. Dyeing and printing: It can dissolve dyes in fabric dyeing and printing processes, ensuring uniform color distribution and penetration.

2. Stain Cleaning: As a stain remover, it effectively dissolves adhesives, gum, and oils on fabrics without leaving stains.

3. In the field of adhesives, ethyl acetate can be dissolved with chemical products such as perchlorethylene resin, polystyrene, rosin, and polyurethane. It can be used to prepare a variety of solvent-based adhesives and can also be used in the production of artificial pearls.

4.Extraction solvents in the pharmaceutical industry: used for the extraction and purification of antibiotics, certain vitamins and other active pharmaceutical ingredients (APIs). Intermediates: In the synthesis of various drugs, ethyl acetate is the key solvent or reactant.

5. Metal hydrometallurgy extraction agent, extracting many compounds (phosphorus, tungsten, arsenic, cobalt) from aqueous solution.

6.In the agricultural industry, ethyl acetate is utilized for its solvent properties in pesticide and herbicide formulations. It dissolves active ingredients for pest control solutions, ensuring they can be evenly spread and absorbed by plants.

• Ethyl acetate is highly volatile and is one of the most widely used fatty acid esters. Based on its strong volatile properties, ethyl acetate is used to produce printing inks for packaging products. In this way, during the printing process, the ink dries easily and solidifies quickly. Ethyl acetate also has the effect of increasing the fragrance of the ink. Ethyl acetate is also a quick-drying solvent for nitrocellulose, ethylcellulose, cellulose acetate and neoprene.

• Ethyl acetate has a fruity aroma.

1. In the production of alcoholic beverages such as brandy, whiskey, rum, rice wine, white wine and other alcoholic beverages, ethyl acetate is added to make the wine have a rich aroma. The types of flavor components in alcoholic beverages include alcohols, esters, acids, aldehydes and ketones, acetals, aromatic compounds, nitrogen-containing compounds and furan compounds. Esters are aromatic compounds that play an important role in various flavored alcoholic beverages and are the main factor in forming the rich aroma of alcoholic beverages. Ethyl acetate is an important aroma component of alcoholic beverages.

2. Ethyl acetate is widely used as a fruit flavoring agent in cakes, candies, ice cream and other foods, and is widely used in the preparation of banana, pear, peach, pineapple, grape and other flavoring food flavorings.
