Resumen:
Research
in the field of the catalytic oxidation of sulfides is promoted due to
several reasons: (a) the synthesis of different chemically and
biologically important molecules and (b) the removal of sulfur from
industrial products and wastes, in order to comply with environmental
legislations. The oxidation of 2-(methylthio)benzothiazole was chosen
as model reaction for this study since this substrate is used in
distinct industrial processes and the corresponding sulfoxide and
sulfone are more biodegradable than the substrate. An
important challenge in this respect is to make this process
environmentally friendly, by strategies such as using nontoxic
solvents, green oxidants and energy-efficient
catalytic methods. In this regard, hydrogen peroxide as cheap and
environmentally friendly oxidant which only produce water and oxygen as
side products is an attractive oxidant for oxidation of organic
compounds. To promote the oxidant efficiency, modified ZSM-5 zeolites
were evaluated as catalysts for sulphide oxidation.
