Как получить уксусный альдегид из пропаналя?

Ch3ch2coh+h2=ni= ch3ch2ch2oh
ch3ch2ch2oh = h2so4 >200 C= ch3ch=ch2
ch3ch=ch2=[o]=Ch3cooh + co2+ h2o
Ch3Cooh =[H]= Ch3Coh + h2o
[O] -окислитель
[H]- восстановитель

CH3-CH2-COH +H2 -> CH3-CH2-CH2OH
CH3-CH2-CH2OH t(H2SO4) -> CH3-CH=CH2 + H2O
5CH3-CH=CH2 +8KMnO4 + 12H2SO4 -> 5CH3COH +5CO2 + 4K2SO4 +8MnSO4 +17H2O

 CH3-CH2-COH + [O] -> CH3-CH2-COOH
CH3-CH2-COOH + KOH -> CH3-CH2-COOK +H2O
CH3-CH2-COOK +KOH t -> CH3-CH3 + K2CO3
C2H6 -> C2H2 + 2H2
HC≡CH + HOH -> CH3-COH
