The kinetic data for reactions between aromatic acids, i.e. benzoic acid, salicylic acid and basic copper carbonate in the solid state have been recorded. The measurements have been made at various temperatures for fixed sizes of the particles at constant compression. The products are characterised by infrared and reflectance spectra. The reactions are diffusion-controlled with activation energy of 71.8 and 115.0±5 kJ mol−1 for the formation of Cu(II) benzoate and Cu(II) salicylate respectively.
