CH2=CH-OOC-CH2-CHO + H2O (H+, t°) → CH3CHO (A) + HOOC-CH2-CHO (E)
CH3CHO + 2AgNO3 + 3NH3 + H2O (t°) → CH3COONH4 (B) + 2Ag + 2NH4NO3
CH3COONH4 + NaOH → CH3COONa (C) + NH3 + H2O
CH3COONa + NaOH (CaO, t°) → CH4 + Na2CO3
HOOC-CH2-CHO + 2AgNO3 + 4NH3 + H2O (t°) → CH2(COONH4)2 (F) + 2Ag + 2NH4NO3
CH2(COONH4)2 + 2NaOH → CH2(COONa)2 (G) + 2NH3 + 2H2O
CH2(COONa)2 + 2NaOH (CaO, t°) → CH4 + 2Na2CO3
