Abstract
Benzothiazole sulphene amides are obtained from dibenzothiazolyl disulphide and water-soluble amines in the absence of an oxidizing agent and in the presence of aqueous alkali in a high yield and with very good stability in storage by placing the amine solution in water and simultaneously adding dibenzothiazolyl disulphide and aqueous alkali from separate storage vessels.
