Resumen:
Lacunary tungstophosphate compounds with Keggin structure modified with transition metal ions [PW11O39M(HzO)]´, where M: Ni2+, Co2+, Cu+* or Zn+,were synthesized and supported on activated. carbon to obtain the PWI1MC catalysts. The activity and selectivify of the catalysts in the sulfoxidation reaction of 2-(methylthio)-benzotbiazole was evaluated. The conversion values decreased in the following order pWllNiC > PWllCuC > PWllCoC > PW11ZnC, with selectivities to sulfoxide higher than 69%.The catalyst could be ie-used without appreciable loss of the catalytic activity at least for three times.
