1) CH4 -> C2H2 -> CH3-COH -> CH3-COOH
    1. 2CH4 -> 1500 C -> C2H2 + 3H2
    2. C2H2 + H2O -> Hg(+2) -> CH3-COH
    3. CH3-COH + Ag2O -> CH3-COOH + 2Ag
2) (CH3COO)2Zn <- CH3-COOH -> CH3-COOK
    1. 2CH3-COOH + ZnO -> (CH3COO)2Zn + H2O
    2. CH3-COOH + KOH -> CH3-COOK + H2O
3) H-COOH -> H-COOC2H5
    1. H-COOH + CH3-CH2OH -> H-COOC2H5 + H2O
