СH3COH + H2 -> CH3-CH2-OH    (p, kat)

CH3-CH2-OH + HBr = CH3-CH2-Br + H2O   (H)

CH3-CH2-Br  + KOH(спирт) -> CH2=CH2 + KBr + H2O  (t)

CH2=CH2 + H2O -> CH3-CH2-OH   (kat)

CH3-CH2-OH + CuO -> CH3COH + Cu + H2O

б)  HCOH  + H2 -> CH3-OH   (p, kat)

CH3-OH + HCl =  CH3-Cl + H2O   (H)

CH3-Cl + 2Na + Cl-CH3  ->  CH3-CH3  +  2NaCl

CH3-CH3 + Cl2 -> CH3-CH2-Cl + HCl   (hy)

CH3-CH2-Cl + KOH(спирт) -> CH3-CH2-OH + KCl + H2O (t)

CH3-CH2-OH + CuO -> CH3-COH + Cu + H2O

CH3COH + Ag2O -> CH3COOH + 2Ag     (NH3)
