Abstract: The invention is the extrusion of sulfur from thiodinitriles to obtain the corresponding dinitrile by heating the thiodinitrile at a temperature of 200 DEG to 700 DEG C. For example, sulfur is extruded from thiodipropionitrile to obtain adiponitrile. This extrusion reaction can be either a strictly thermal reaction employing no other reactant or a reaction conducted in the presence of other gases, liquids or solids.
