As a child, we used to play with glue by applying it on our hands and try to peel it off in one piece, but we also have very much got used to the smell of it, don’t we? Have you ever noticed the familiar odour of glue and nail polish much? Which is so similar to pear drops. It is because you have smelled ethyl acetate. It’s a common ingredient in the production of glue.
What is Ethyl Acetate?
Ethyl acetate or ethyl ethanoate is an organic compound with the molecular formula CH3-COO-CH2-CH3. It is one of the simplest carboxylate esters which is commonly used as a solvent in chemical industries such as adhesives and alcoholic beverages, ethyl acetate responsible for the peculiar taste we get from old wines. It is a colourless liquid with a sweet and fruity odour that most people find pleasing. Generally, manufacturers produce ethyl acetate on an extensive scale for supplying.
The principal function of ethyl acetate is to dissolve the resin, modify & then reduce the drying rate and control the viscosity of the product. Ethyl acetate is used as a solidifying agent in the manufacture of essences and some powder products. At all proportions, it can be combined with commonly used organic solvents making it a miscible substance.
Physical Properties of Ethyl Acetate:
- The mass/ density is 88.1 g. mol-1
- Its colourless liquid
- It has a pleasant fruity odour
- The melting point of ethyl acetate is -88.6◦C
- The boiling point is 77.1◦C
- It is soluble in water and other organic solvents such as benzene, toluene, chloroform, and acetone.
- Ethyl acetate and some esters can be hydrolysed to be corresponding to ethanol and carboxylic acid.
- By reaction with sodium hydroxide by using acids or bases as catalysts it gives acetic acid and ethanol by a two-step mechanism.
- The transesterification reaction is held by substitution of methoxy groups from the ester to the R-group from alcohol.
Role of ethyl acetate in glue production:
- Ethyl acetate-based solvent glue exhibits a stronger bond strength compared to traditional adhesives and has a higher resistance to peeling.
- In hot glue solid adhesives, they are popular because of their use in the wide range of common materials they can join.
- Using a glue gun is one way of applying hot adhesives. The gun melts the solid tube-shaped glue, then allows the hot liquid to pass through its barrel onto any material, it sticks as the temperature of the glue cools and dries. The hot ethyl acetate solvent makes the bond almost impossible to break.
Uses of Ethyl Acetate:
As a solvent in the production of
- Glues/ adhesives
- It is a very useful raw material to get fragrance flavours like banana, strawberry, and pineapple.
- It is also used in perfumes and jelly
- Ethyl acetate is a vital reagent
- In wines, it helps to give a particular taste
- Decaffeination of coffee beans and tea leaves.
- As an activator & hardener
Ethyl acetate is used in extractions as solvents and in column chromatography, Ethyl acetate suppliers produce Tons of Ethyl Acetate for various applications per year. The major reason for using ethyl acetate in the manufacturing of glue is, it is a strong binder. The manufacturers of ethyl acetate have significantly grown over the years across various industries like resins, clothing, paper, cars, shoes, etc.
Drawbacks of Ethyl Acetate:
Though it is a useful compound, ethyl ethanoate is highly hazardous to health if one is not careful while handling it.
- Ethyl acetate can cause irritation in the eyes, nose, and throat
- Sometimes, ethyl acetate can lead to drowsiness, weakness, and unconsciousness
- Constant usage and inhalation of the chemical creates harmful effects on the respiratory tracts
- Depression of the central nervous system and lethal if used in high concentration
- Can cause cornea damage, liver damage, and eruptions of the skin
We should be very cautious with ethyl acetate and take proper measures to prevent any health damage it may lead to.
