Desuliurization of dibenzothiophene is effected in 82% yield by means of methanol and a sulfidcd cohaltous oxide‐molylxlic oxide‐aluminum oxide catalyst at 450° and ca. one atmosphere pressure in a flow system. The methanol serves as a hydrogen donor and methylating agent to form biphenyl (main product), 3‐ and 4‐methylbiphenyls, and fluorene.
