Draw up a chain of transformations to obtain ethyl acetate from ethane, write down the equations
Draw up a chain of transformations to obtain ethyl acetate from ethane, write down the equations of the corresponding reactions.
Let’s write down the solution:
1. Let’s compose a chain of transformations:
C2H6 – C2H4 – C2H5 – OH – CH3 – SON – CH3 – COOH – CH3COO – C2H5;
2. Let us write down the reaction equations:
Н3С – СН3 = Н2 + Н2С = СН2 – dehydrogenation reaction, ethylene was obtained;
H2C = CH2 + H2O = CH3 – CH2 – OH – hydration, ethanol is released;
CH3 – CH2 – OH + CuO = CH3 – COH + Cu + H2O – alcohol oxidation, ethanal was formed;
CH3 – СОН + Ag2O = CH3 – COOH + 2Ag – oxidation of aldehyde, acetic acid obtained;
CH3 – COOH + C2H5 – OH = CH3COO – C2H5 + H2O – esterification occurs in the presence of sulfuric acid, ethyl acetate is released.
The equations of the transformation chain show the relationship between hydrocarbons and oxygen-containing organic substances. The final product, ethyl acetate (ethyl acetate), is used in perfumery as a basis for the manufacture of colognes and perfumes.
