Question

Складіть рівняння реакцій для здійснення перетворень за схемами:
а) C2H4-->C2H5OH-->CH3COOH-->CH3COOH3-->CH3COONa
б) C3H6-->C3H7OH-->C2H5COOH-->C2H5COOC2H5-->C2H5COOK

Answer 1

а) C2H4-->C2H5OH-->CH3COOH-->CH3COOСH3-->CH3COONa

C2H4 + H2O == C2H5OH

3C2H5OH + 2K2Cr2O7 + 8H2SO4 ==3CH3COOH + 2K2SO4 + 2Cr2(SO4)3 +

+ 11H2O

CH3COOH + CH3OH == CH3COOCH3 + H2O

CH3COOCH3 + NaOH = CH3COONa + CH3OH

б) C3H6-->C3H7OH-->C2H5COOH-->C2H5COOC2H5-->C2H5COOK

C3H6 + H2O == C3H7OH

3C3H7OH + 2K2Cr2O7 + 8H2SO4==3C2H5COOH + 2K2SO4 + 2Cr2(SO4)3 +

+ 11H2O

C2H5COOH + C2H5OH == C2H5COOC2H5 + H2O

C2H5COOC2H5 + KOH == C2H5COOK + C2H5OH
