Abstract: The solid solid state reaction of 2,2'-(p-phenylenedimethylenethio)diacetic acid with cobalt acetate tetrahydrate has been studied. XRD, IR, ESR, TG-TA and elemental analysis were used to characterize the solid product. The kinetics of the isothermal solid state reaction was investigated by using the electrical conductivity measurement. The kinetics of this system conforms to a A3 mechanism, the activation energy is calculated to be Ea=104.7 kJ/mol.

Key words: p-phenylenedimethylenethio diacetic acid, cobalt acetate tetrahydrate, solid state reaction, kinetics
