無水酢酸の合成法とその応用

抄録

The recent advances in the preparation of acetic anhydride by carbonylation of methyl acetate and/or dimethyl ether using catalytic systems including Rh or Ni, and methyl iodide or some other catalysts are reviewed. In contrast with the case of methanol, modification of catalyst by combining with organic N-, P-, or As- compound improves the rate of reaction. The addition of cocatalysts, such as lithium salts and/or Cr (CO) ₆, also improves the activity of the catalyst.
The reaction mechanisms of these reactions are also discussed.
In connection with this reaction, the preparations of ethylidene diacetate, vinyl acetate and acetaldehyde are also mentioned.
