Giải thích các bước giải:
(1) C12H22O11 + H2O -> C6H12O6 + C6H12O6
(2) C6H12O6-> 2C2H5OH +2CO2
(3) C2H5OH + O2 -> CH3COOH + H2O
(4) CH3COOH + C2H5OH -> H2O+CH3COOC2H5
(5) CH3COOC2H5 + NAOH -> C2H5OH + CH3COONA
(6) CH3COONA + H2O -> CH3COOH + NAOH
(7) CH3COOK + NAOH -> CH4 + K2CO3 + NA2CO3
(8) CH4 +O2 -> CO2 +2H2
(9) 2CO2 + 3H2O -> C2H5OH + 3O2
