Abstract

Bis-benzthiazolyl-disulphide is obtained by reacting an aqueous suspension of mercaptobenzthiazole, or an aqueous solution of a salt of mercaptobenzthiazole, with nitrosyl chloride, or with a mixture of nitric oxide and nitrosyl chloride or nitric oxide, nitrosyl chloride and chlorine. The nitrosyl chloride is obtained by reacting nitric oxide with chlorine, and the nitric oxide formed by reacting nitrosyl chloride with mercaptobenzthiazole, is reacted with further chlorine and recycled. The reaction is carried out at 0 DEG to 50 DEG C. by passing the gas mixture into an aqueous suspension containing 1 to 15% by weight of mercaptobenzthiazole. Ammonium ions may be present in the suspension to reduce the particle size of the product. In examples bis-benzthiazolyl-disulphide is obtained from mercaptobenzthiazole and from its calcium salt.
