    摘要： METHOD OF MAKING AMMONIA AND CHLORINE FROM AMMONIUM CHLORIDE BY THERMAL DISSOCIATION WITH A CATALYST MASS COMPRISING A PARTLY REDUCED METAL OXIDE FIXING THE CHLORINE ION AS A METALLIC CHLORIDE WHILE THE LIBERATED AMMONIA GAS PASSES OFF WITH WATER VAPOR AND IS CAPTURED. IN A SUBSEQUENT STEP OF OXIDATION THE CHLORINE IS LIBERATED AND THE METAL OXIDE IS IN A HIGHER STATE. THIS OXIDE IS AGAIN PARTLY REDUCED AND THE PROCESS IS REPEATED WITH NEW AMMONIUM CHLORIDE. IN THE IMPROVEMENT THE CATALYST MASS IS MADE OF MOLTEN ALKALI METAL CHLORIDES CONTAINING IN SUSPENSION A FINELY DIVIDED METAL OXIDE SUCH AS FE, NI, CO, AND PREFERABLY FE.
