Abstract: This invention relates to a photosensitizer which is bound to a titanate polymer, a method of preparing the bound photosensitizer and a process for using the bound photosensitizer. The photosensitizers which may be used in the invention include rose bengal, azure blue, rhodamine B, fluorescein and eosin. The photosensitizer is attached to the titanate by displacing a ligand on the titanate with a hydroxyl group on the photosensitizer. Finally, the bound photosensitizer may be used to oxidize undesirable oxidizable compounds present in a hydrocarbon or aqueous fraction. One specific example is the sweetening of kerosene which involves oxidizing the mercaptans contained in the kerosene to disulfides.
