| Abstract: | The anionic manganese (III) porphyrin was immobilized onto crosslinked poly(benzylpicoline‐co‐styrene) resin through coordinate linkage. The immobilized metalloporphyrin was employed as a heterogeneous catalyst for the hydroxylation of cyclo‐octane by NaOCl. The observed reaction rates depend on experimental parameters such as stirring speed, substrate amount, temperature, and catalyst amount. The influence of different polymer‐based axial ligands, particle size, and percent crosslinking of the polymer support was also discussed. The imidazole‐based polymer supports show higher rate constant values than the pyridine‐based supports. The catalyst shows significant decrease in catalytic activity on recycling. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 104–111, 2000 |
