Beschreibung
Zusammenfassung:	The invention relates to a process for preparing a thiuram disulfide comprising reacting a secondary amine with carbon disulfide in the presence of oxygen and a metal catalyst in the absence of a solvent using a secondary amine of which the corresponding thiuram disulfide is liquid under the reaction conditions. The invention also pertains to the use of said thiuram disulfides as vulcanization accelerators or lubricant oil additives.
