Ethyl Acetate.
Ethyl acetate is a mutual illustration of an ester of an organic acid.
Preparation. It is prepared inwards manufacture as well as inwards the laboratory yesteryear heating ethanol alongside glacial acetic acid inwards the presence of concentrated sulphuric acid.
50 ml of ethanol as well as fifty ml of glacial acetic acid are taken inwards a 250 ml round-bottomed flask, as well as sixteen ml of concentrated H2SO4, added to it. The mixture is refluxed for minutes yesteryear fixing a water-condenser alongside the
flask. The apparatus is as well as thence changed to distillation using water-condenser. All fractions distilling upward to 80°C are collected. The distillate is treated alongside 2M sodium carbonate solution inwards a separating funnel to take acids. The oily layer inwards the funnel is as well as thence treated alongside concentrated calcium chloride solution to take ethanol. The production is lastly dried over anhydrous calcium chloride as well as distilled. The fraction passing over betwixt 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 inwards H2O but freely soluble inwards chloroform, alcohol as well as ether. It is a neutral non-toxic liquid. It gives all the full general reactions of esters described before.
Ethyl acetate uses.
Ethyl acetate is used.
- As a solvent inwards industry, notably for lacquers as well as resins.
- In artificial fruit flavors.
- In organic synthesis e.g., for making ethyl acetoacetate.
The ethyl acetate chemic formula is CH3COOCH2CH3 and its condensed formula is C4H8O2 Ethyl acetate is ordinarily abbreviated EtOAc. Ethyl acetate tooth volume is 88.106 g mL-1.It is chemic construction tin live written every bit below, inwards the mutual used for organic molecules.
