The reactions of benzoic anhydride with excess cupric oxide are carried out in cyclohexane as an inert solvent at several temperatures for 1 hour. The conversion of benzoic anhydride into a copper benzoate, which is different from the well-known copper (I) or (II) benzoates, was determined by three methods (solvent extraction, elementary analyses and hydrolysis) which showed the consistent results (20.9 mol %, 27.3 mol % and 23.4 mol % respectively at 240°C, 1 hr). An increase in conversion was observed at temperatures higher than 240°C. The X-ray diffraction diagram of the product containing the above copper salt differed from those of cupric oxide, cuprous benzoate and cupric benzoate. 1974, The Chemical Society of Japan.
