• Precursor to acetic anhydride

Production

Synthesis

• glacial acetic acid + phosphorus trichloride

  3 CH₃COOH + PCl₃⟶3 CH₃COCl + H₃PO₃

• acetic anhydride with hydrochloric acid

  O(CH₃CO)₂ + HCl → CH₃COOH + CH₃COCl

• dichlorocarbonyl and acetic acid

  COCl₂ + CH₃COOH → HCl + CO₂ + CH₃COCl
