Ethyl acetate is an organic ester compound with the chemical formula C4H8O2, which is a clear, colorless liquid with a fruity odor. This compound is highly flammable and ignites at minus 4 degrees Celsius. It should be noted that its melting point is minus 83 degrees Celsius and its boiling point is 77.1 degrees Celsius. This compound is also known as acetic acid ethyl ester, acetoxyethane, acetic ether, and ethyl acetate in the market.
Ethyl acetate is a substance that is highly soluble in all known organic solvents, including alcohols, glycols, ketones, and esters. However, it has a solubility of less than 25% in water at room temperature, i.e. 25°C, which increases with increasing temperature. This compound is also very important in industry as one of the best solvents with a low boiling point and high evaporation rate.
Ethyl acetate production process
Ethyl acetate production process in industry is usually carried out by the Fischer esterification reaction of ethanol and acetic acid. The resulting compound is converted to an ester at a rate of about 65% at room temperature, i.e. 25°C. Of course, an acidic catalyst can be used to speed up this reaction and to establish the reaction equilibrium by removing water.
Another method used to produce ethyl acetate in industry is the production of this compound from the Tishchenko reaction with acetaldehyde in the presence of an alkoxy catalyst, which is as follows:
2 CH3CHO → CH3COOCH2CH3
Also, a specialized and industrial method of producing ethyl acetate is carried out using the catalytic decomposition of ethanol. This method is much more economical than producing this compound by esterification.

It can be said that it is used as a solvent and diluent in thinner, cellulose coatings, and in the paint and resin industries because its cheap price and pleasant smell eliminate the need for fragrances in its products. The main and most important use of ethyl acetate is in the printing and packaging industries, where it is used as a printing ink in flexo, helio, and rotogravure printing machines. It is also used as a raw material in the production of printing inks for printing machines.
Other uses of ethyl acetate include its use in food products, in the production of synthetic fruit essential oils and flavors, and in the pharmaceutical industry and the purification process of antibiotics, where this compound plays an important and practical role.
The process of producing ethyl acetate in industry is usually carried out by the Fischer esterification reaction of ethanol and acetic acid. An acid catalyst can be used to accelerate this reaction. The second method for producing ethyl acetate is to produce this compound from the Tishchenko reaction with acetaldehyde in the presence of an alkoxy catalyst.
In discussing the safety and dangers of ethyl acetate, it can be said that since this compound is present in the tissues of the human body, it cannot be considered toxic. Also, according to studies conducted on this substance, scientists have concluded that exposure to ethyl acetate may cause irritation of the eyes, nose, and throat. However, if you are exposed to this compound for a long time, it may cause weakness, drowsiness, and loss of consciousness.
In discussing first aid, it can also be said that if ethyl acetate comes into contact with the skin or eyes, be sure to wash the area with plenty of water for 15 minutes. Be sure to take out the person’s contaminated clothes and wash them before reusing them. Also, if this mixture is swallowed, drink plenty of water and see a doctor immediately. Finally, if ethyl acetate is inhaled, move the person to fresh air. If necessary, give artificial respiration and use oxygen until a doctor is consulted.
