Solve the transformation chain: C2H6-C2H5Br-C2H4-C2H5OH-CH3COH-CH3COOH – CH3COOCH3-CH3COONA

1. Bromination of ethane in UV light.

C2H6 + Br2 = C2H5Br + HBr.

2. Irradiation of ethylene in two stages:

Würz reaction.

2C2H5Br + 2Na = C4H10 + NaBr.

Cracking of butane.

C4H10 = C2H4 + C2H6.

3. Reaction Butlerov – hydration under the action of a catalyst.

C2H4 + H2O = CH3-CH2-CH.

4. Oxidation of ethanol to ethanal in the presence of silver salts.

CH3-CH2-CH + O2 => CH3-CH = O + H2O.

5. Oxidation of ethanal to acetic acid.

2CH3-CH = O + O2 => CH3-COOH.

6. Getting methyl acetate. This reaction takes place in the presence of conc. H2SO4.

CH3-COOH + CH3OH = CH3-COO-CH3 + H2O.

7. Obtaining sodium acetate.

CH3-COO-CH3 + NaOH = CH3-COONa + H2O.
