Ethyl acetate is a common example of an ester of an organic acid.
It is prepared in industry and in the laboratory by heating ethanol with glacial acetic acid in the presence of concentrated sulphuric acid.
50 ml of ethanol and 50 ml of glacial acetic acid are taken in a 250 ml round-bottomed flask, and 16 ml of concentrated H2SO4, added to it. The mixture is refluxed for minutes by fixing a water-condenser with the
flask. The apparatus is then changed to distillation using water-condenser. All fractions distilling up to 80°C are collected. The distillate is treated with 2M sodium carbonate solution in a separating funnel to remove acids. The oily layer in the funnel is then treated with concentrated calcium chloride solution to remove ethanol. The product is finally dried over anhydrous calcium chloride and distilled. The fraction passing over between 74-79°C is collected.
Ethyl acetate properties.
Ethyl acetate is a colorless liquid, bp77°C, having a pleasant fruity odour. It is sparingly soluble in water but freely soluble in chloroform, alcohol and ether. It is a neutral non-toxic liquid. It gives all the general reactions of esters described before.
Ethyl acetate uses.
Ethyl acetate is used.
- As a solvent in industry, notably for lacquers and resins.
- In artificial fruit flavors.
- In organic synthesis e.g., for making ethyl acetoacetate.
The ethyl acetate chemical formula is CH3COOCH2CH3 and its condensed formula is C4H8O2Ethyl acetate is commonly abbreviated EtOAc. Ethyl acetate molar mass is 88.106 g mL-1.It is chemical structure can be written as below, in the common used for organic molecules.
Ethyl acetate hazards.
Ethyl acetate can also cause irritation when it comes into contact with the eyes or skin.It is steady yet it is contradictory with solid oxidizing operators.Ethyl acetate acid derivation is very combustible, just as poisonous when ingestion or breathed in, and this synthetic can be truly harming to inner organs on account of rehashed or delayed presentation.
