A catalyst for oxidizing soluble alkali mercaptide compounds to disulfide compounds in an aqueous alkaline solution, comprising a metal complex of 2,3, 7,8,12,13,17,18-tetra [1,2-benzo-4 (4'-phthaloyl)]-porphyrazine-2-,22,23,24-tetraene, or a substituted derivative thereof having the structural formula: ##STR12## where M is a metal selected from the group consisting of iron, manganese, chromium, magnesium, copper, nickel, zinc, titanium, hafnium, thorium, tin, lead, columbium, tantalum, antimony, bismuth, molybdenum, palladium, platinum, silver, mercury, vanadium and cobalt and A is hydrogen or an alkali metal.
- 2. The catalyst of claim 1 wherein M is cobalt or vanadium.
- 3. The catalyst of claim 2 wherein M is cobalt.
- 4. The catalyst of claim 2 wherein M is vanadium.
- 5. The catalyst of claim 2 wherein M is cobalt and A is hydrogen.
- 6. The catalyst of claim 2 wherein M is cobalt and A is sodium.
- 7. The catalyst of claim 2 wherein M is vanadium and A is sodium.
