Tridentate metal ligands of certain pyridine phosphonic acids |
摘要 |
Novel pyridine phosphonate ligands are disclosed that when combined with polyvalent metals results in useful catalyst compositions for the conversion of hydrogen sulfide to solid sulfur. Catalysts containing these novel ligands exhibit resistance to metal precipitation and demonstrate little or no oxidative chemical degradation when employed to convert hydrogen sulfide to elemental sulfur.
