Abstract
In a method for reducing the content of polychlorinated dibenzodioxins and -furans in the exhaust gas of chemical high temperature processes handling process materials, amides or organic oxides are made available to the process under the conditions under which the polychlorinated dibenzodioxins and -furans are generated, which amides comprise of at least one of the group consisting of amidosulfonic acid, hydroxyl amino sulfonic acid and sulfamid in an amount of 0.5 to 10% of the process material.

A method for reducing the content of polychlorinated dibenzodioxins and -furans in the exhaust gas of process materials subjected to chemical high temperature processes, comprising the steps of:
- providing under the conditions under which said polychlorinated dibenzodioxins and -furans are generated, amides of organic acids, which amides comprise at least one of the group consisting of amidosulfonic acid, hydroxylamino sulfonic acid and sulfamid in an amount of 0.5 to 10% of the process material.
