C2H5OH --- C2H4O --- CH3COOH --- CH3COOC2H5 --- CO2
       !                                 !
    CO2                    (CH3COO)2Zn

С₂H₅OH + 3O₂ = 2CO₂ + 3H₂O
С₂H₅OH  + CuO = CH₃-COH + Cu + H₂O
CH₃-COH + Ag₂O = CH₃-COOH + 2Ag
2CH₃-COOH + Zn = (CH₃-COO)₂Zn + H₂
CH₃-COOH + С₂H₅OH  = CH₃-CO-O-С₂H₅ + H₂O
CH₃-CO-O-С₂H₅ + 5O₂ = 4CO₂ + 4H₂O
