Make a reaction equation: sodium acetate → acetic acid → chloroacetic acid.

Let’s compose the equations:
CH3COONa + NaOH = CH4 + Na2CO3 – exchange, methane is released;
CH4 + Cl2 = CH3Cl + HCl – chloromethane is formed;
2CH3Cl + 2Na = H3C – CH3 + 2NaCl;
C2H6 = C2H4 + H2 – dehydrogenation obtained ethylene;
C2H4 + H2O = C2H5OH – ethanol is formed;
С2Н5ОН + CuO = C2H4O + Cu + H2O – oxidation of ethanol, ethanal is released;
C2H4O + Ag2O = CH3COOH + 2Ag – acetic acid obtained;
CH3COOH + Cl2 = CH2Cl – COOH + HCl – substitution, chloroacetic acid was released.
The end product of the reactions, chloroacetic acid, is used in the synthesis of dyes.
