| Abstract: | he chemical equilibrium and reaction kinetics of the isomerization of sodium cis-hexahydroterephthalate in aqueous solution were studied in the temperature ranges of 220￣ 280℃ and 180￣220℃ respectively. It was proved that this reaction is an exothermic,reversible, and first order reaction. Its equilibrium constant is related to temperature by The reaction heat is ΔH0=8. 492 (kJ/mol)Its reaction rate constant is with activation energy of |
