In a process for the production of benzothiazole-2-sulphenamides, a 2-mercaptobenzothiazole in the form of a particulate solid or a dispersion of a particulate solid in a liquid carrier is added gradually and concurrently with an aqueous solution of sodium hypochlorite to a solution of an amine in a mixture of water and a water-miscible organic solvent, the amount of amine being not more than 1.25 moles per mole of 2-mercaptobenzothiazole. A feature of the process is that it represents a significant improvement over prior art methods for the production of sulphenamides derived from secondary amines such as dicyclohexylamine and diisopropylamine.
