Reaction Steps

This example is an inventive run illustrating the use of another soluble cobalt-containing catalyst system. The run also suggests that because of the enhanced catalyst activity of the cobalt-containing catalyst system, the reaction can be operated with less alcohol present. Into a 300 milliliter stainless steel reactor equipped as described in Example I was charged 12 grams of methyl alcohol, 2 grams of sodium hydroxide, 0.1 gram of cobalt acetate and 86 grams (0.74) moles of cyclohexyl mercaptan. The reactor was pressured to 240 psig with nitrogen, heated to 55° C. (131° F.) and then pressured to 300 psig with oxygen. The reaction was complete in 3 hours. The effluent was water washed and the oil layer dried on a Rotovap at 90°-100° C./20-40 Torr. (mm) to give a 100 percent selectivity and 83.8 percent yield of dicyclohexyl disulfide.
