Abstract

Chlorine is prepared by catalytic oxidation of a hydrogen chloride stream having a content of sulfur in elemental or bonded form of less than 100 ppm, preferably less than 50 ppm, more preferably less than 5 ppm, most preferably less than 1 ppm, based on the weight of the hydrogen chloride stream.
