CH3-CH2-CH2-OH + (2O) --KMnO4 / H2SO4 --- CH3-CH2-COOH + H2O

CH3-CH2-COOH + NaOH ------ CH3-CH2-COONa + H2O

CH3-CH2-COONa + NaOH ---Cao / heat --- CH3-CH3 + Na2CO3

CH3-CH3 + Cl2 ------ CH3-CH2-Cl + HCl

CH3-CH2-Cl + KOH ---boiling---CH3-CH2-OH + KCl

CH3-CH2-OH-----H2SO4 / 180 c----CH2=CH2 + H2O

CH2=CH2 + H2O + (O) ---KMnO4 / KOH --- CH2(OH)-CH2(OH)i
