An unusual experimental observation for a gas-solid reaction system, viz. disproportionation of potassium benzoate to terephthalate in the presence of CO,, is reported. A uniform mixture of potassium benzoate and cadmium chloride as catalyst was used in the form of cylindrical pellets. It was observ
