A solution of 40 g (0.24 mol) of 2-mercaptobenzothiazole, 22.4 mg (0.1×10-3 mol) of Mn(OAc)2. 4H2O and 4.08 g (0.24 mol) of ammonia in 120 g of methanol is in the manner and reaction equipment described in Example 1 reacted with oxygen at an oxygen pressure of 4 bar and a reaction temperature of 55° C. After a reaction time of 3 hours, one obtains dibenzo thiazyl disulfide at a yield of 35.9 g, corresponding to 90.3% of theoretical. The conversion rate is determined to be 92.1%.
