Reactions in which Acetic anhydride is involved

  • C6H5OCH3 + (CH3CO)2O → CH3OC6H4C(O)CH3 + CH3COOH
  • Co(CH3COO)2 + 2H2O + 4CH3CO{X} -> Co{X}2 + 2(CH3CO)2O + 2CH3COOH + 2H{X} , where X = Cl Br
  • /`|O|\O/`|O|\ + H2S → /`|O|\SH + /`|O|\OH
  • AlCl3 + 3(CH3CO)2O "180^oC"--> Al(CH3COO)3 + 3CH3COCl
  • 2|\\|`/<`\`|/>|<`/><_(a20)>\OH + /`|O|\O/`|O|\ "26-28^oC"--> 2|\\|`/<`\`|/>|<`/><_(a20)>\O/`|O|\ + H2O
