Abstract

Die Erfindung betrifft ein Verfahren zur elektrochemischen Herstellung von Chlor aus wässrigen Lösungen von Chlorwasserstoff in einer Elektrolysezelle, umfassend eine Anodenkammer und eine Kathodenkammer, wobei die Anodenkammer durch eine Kationenaustauschermembran von der Kathodenkammer getrennt ist, die Anodenkammer eine Anode und die Kathodenkammer eine Gasdiffusionskathode enthält, und in die Anodenkammer die wässrige Lösung von Chlorwasserstoff und in die Kathodenkammer ein sauerstoffhaltiges Gas eingeleitet wird, wobei der Sauerstoffdruck in der Kathodenkammer mindestens 1,05 bar beträgt.
