Resumo: Tetraphenylporphyrin complexes containing Fe(III), Mn(III) or Co(II) metal ions were synthetized , characterized and employed in limonene oxidation. The experiments were carried out in different solvents (acetonitrile, ethyl acetate or methylene chloride) and tert-butylhydroperoxide (TBHP, 70% in water) and sodium hypochloride (NaOCl, 30% in water) were used as oxidant agents. The systems showed high activity on limonene oxidation and low selectivity. The conversion showed dependence on the oxidant agents but it was lightly influenced by the catalysts and solvents

Foram utilizados três solventes (acetato de etila, acetonitrila e diclorometano) e dois agentes doadores de oxigênio (hidroperóxido de terc-butila e hipoclorito de sódio) de acordo com planejamento de experimentos. Os sistemas propostos apresentaram altos valores para a conversão do limoneno com baixa seletividade a carvona/epóxidos. A conversão se mostrou fortemente dependente do agente oxidante utilizado e pouco influenciada pelo complexo metálico e solventeUniversidade Estadual De Maringá2008-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/153310.4025/actascitechnol.v26i1.1533Acta Scientiarum.
