Abstract

Disclosed is a method for producing high-purity liquid chlorine wherein a raw material chlorine which contains chlorine oxide as impurities is irradiated with light so that the chlorine oxide is decomposed into chlorine and oxygen, and then purification is performed by distillation. Consequently, chlorine oxide impurities can be efficiently removed from chlorine.
