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.
