Hydrodemetallization of water soluble phthalocyanine belonging to the family of dyes used in the textile industry, nickel (II) phthalocyanine tetrasulfonic acid, was performed using microwave radiation in the presence of NiMo/Al₂O₃ and CoMo/Al₂O₃ catalysts. The results were 98 and 97 % for each catalyst, respectively, by a treatment time of 10 minutes, achieving the retention of an amount of metal in the catalyst and also the conversion of the phthalocyanine to N, N-dimethyl octanamine, which has surfactant and antiseptic properties.
