Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Abtrennung aus Kohlenmonoxid aus einem chlorwasserstoffhaltigen Gas, dass die Umsetzung des Kohlenmonoxids mit Chlor zu Phosgen und die anschließende Abtrennung des Phosgens aus dem chlorwasserstoffhaltigen Gas umfasst. Das eingesetzte chlorwasserstoffhaltige Gas entstammt bevorzugt der Phosgenierungs- bzw. Isocyanatbildungsreaktion.
