ABSTRACT:
A method for supporting metalloporphyrins on polybenzimidazole articles is disclosed herein. Microporous polybenzimidazole articles are treated with a strong base to produce an anionized polybenzimidazole article. A metalloporphyrin salt is dissolved in a solvent and is mixed with the anionized polybenzimidazole article to produce a microporous polybenzimidazole metalloporphyrin complex. This compound can be used in the selective oxidation of alkanes, olefins and aromatic compounds and is quite useful in the separation of oxygen from a gas stream. An alternative method of forming this complex by mixing directly the polybenzimidazole particulate with a weak metalloporphyrin salt without the use of a strong base results in lower percentages of substitution then does the principal method.
