| الوصف: | WOS: 000473121900031 PubMed ID: 30856438 In this study, two water-soluble iron porphyrins bearing sulfonate and carboxylate functionalities (FePTS and FePTC, respectively) and their supported analogues were used as catalysts for the oxidation of 2,6-di-tert-butylphenol (DTBP) in a water-methanol mixture. tert-Butyl hydroperoxide (TBHP) was the oxidant and the volume ratio of water to methanol in the mixture was 1-8. The major products of the DTBP oxidation were 3,3'5,5'-tetra-tert-butyl-4,4'-diphenoquinone (DPQ) and 4,4'-dihydroxy-3,3',5,5'-tetra-tert-butylbiphenyl (H(2)DPQ). Also 2,6-di-test-butyl-1,4-benzoquinone (BQ) was the minor product of the oxidation. The results showed that FePTC was more catalytically active than FePTS in the oxidation and gave the highest TON and TOF values in comparison to those for metalloporphyrin and metallophthalocyanine based catalysts in the DTBP oxidation given in the literature. In addition, the ecotoxicity tests of the DTBP oxidation mixtures before and after oxidative catalytic treatment toward Anemia sauna were performed. It was found that the toxicity of the catalytically treated DTBP mixture containing residual DTBP and products was lower than the catalytically untreated DTBP mixture.
