A new thermochemical decomposition cycle of sodium chloxide Tor the preparation of chlorine and sodium hydroxide is presented in this paper. The optimum conditions of the main reactions in the cycle were obtained from a series of experimental results. The heat flow of the cycle system was calculated based on the related thermodynamic equations and thermodgnamic data. The hinetie study with the heterogeneous reaction in the cycle was carried out by means of thermogravimetric method. The result shows that the proposed cycle demonstrates an obviously energy ?saving advantage than all the other methods for production of chlorine and sodium hydroxide. It may become ecnomically competitive with the current elecotrolylic method in future.
