141-78-6 Usage


Flammable liquid

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Health Hazard

Headache, irritation of respiratory passages and eyes, dizziness and nausea, weakness, loss of consciousness.

Extinguishing agent

dry powder, dry sand, carbon dioxide, foam, and 1211 fire extinguishing agent

Irritation data

eye-people 400 PPM


Industrial production of ethyl acetate is mainly classified into three processes.

The first one is a classical Fischer esterification process of ethanol with acetic acid in presence of acid catalyst. This process needs acid catalyst2 such as sulphuric acid, hydrochloride acid, ptoluene sulfonic acid etc. This mixture converts to the ester in about 65% yield at room temperature. 
The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by removal of water.

The second one is Tishchenko Reaction of acetaldehyde using aluminium triethoxide as a catalyst. In Germany and Japan, most ethyl acetate is produced via the Tishchenko process. 
This method has been proposed by two different routes; (i) dehydrogenative process, which uses copper or palladium based catalyst and (ii) the oxidative one, which employs, PdO supported catalysts.

The third one, which has been recently commercialized, is addition of acetic acid to ethylene using clay and heteroploy acid7 as a catalyst. 
The processes, however, have some disadvantages; both the conventional esterification and addition of acetic acid to ethylene need stock tanks and apparatus for several feed stocks. Moreover, they use acetic acid that causes apparatus corrosion. Although Teshchenko Reaction uses only one feed and it is a non-corrosive material, it is difficult to handle acetaldehyde because is not available outside of petrochemical industrial area.
In such circumstances, an improved process of ethyl acetate production is strongly desired.

Ethyl Acetate is an organic ester compound with a molecular formula of C4H8O2 (commonly abbreviated as EtOAc or EA), appears as a colorless liquid. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters), which make it a common solvent for cleaning, paint removal and coatings.
Ethyl acetate is found in alcoholic beverages, cereal crops, radishes, fruit juices, beer, wine, spirits etc. It has a fruity characteristic odor that is commonly recognized in glues, nail polish remover, decaffeinating tea and coffee, and cigarettes. Due to its agreeable aroma and low cost, this chemical is commonly used and manufactured in large scale in the world, as over 1 million tons annually.

Reactivity Profile

Ethyl acetate is also sensitive to heat. On prolonged storage, materials containing similar functional groups have formed explosive peroxides. Ethyl acetate may ignite or explode with lithium aluminum hydride. Ethyl acetate may also ignite with potassium tert-butoxide. Ethyl acetate is incompatible with nitrates, strong alkalis and strong acids. Ethyl acetate will attack some forms of plastics, rubber and coatings. Ethyl acetate is incompatible with oxidizers such as hydrogen peroxide, nitric acid, perchloric acid and chromium trioxide. Violent reactions occur with chlorosulfonic acid. . SOCl2 reacts with esters, such as Ethyl acetate, forming toxic SO2 gas and water soluble/toxic acyl chlorides, catalyzed by Fe or Zn (Spagnuolo, C.J. et al. 1992. Chemical and Engineering News 70(22):2.).

Flammability and hazard characteristics

it is flammable in case of fire, high temperature, and oxidant with burning causing irritated smoke

Air & Water Reactions

Highly flammable. Slightly soluble in water. Ethyl acetate is slowly hydrolyzed by moisture.

Purification Methods

The most common impurities in EtOAc are water, EtOH and acetic acid. These can be removed by washing with aqueous 5% Na2CO3, then with saturated aqueous CaCl2 or NaCl, and drying with K2CO3, CaSO4 or MgSO4. More efficient drying is achieved if the solvent is further dried with P2O5, CaH2 or molecular sieves before distillation. CaO has also been used. Alternatively, ethanol can be converted to ethyl acetate by refluxing with acetic anhydride (ca 1mL per 10mL of ester), the liquid is then fractionally distilled, dried with K2CO3 and redistilled.

Purification and water removal methods

Ethyl acetate generally has a content of 95% to 98% containing a small amount of water, ethanol and acetic acid. It can be further purified as following: add 100mL of acetic anhydride into 1000mL of ethyl acetate; add 10 drops of concentrated sulfuric acid, heat and reflux for 4h to remove impurities such as ethanol and water, and then further subject to distillation. Distillate is oscillated by 20~30g of anhydrous potassium carbonate and further subject to re-distillation. The product has a boiling point of 77 °C and purity being over 99%.
