ABSTRACT:
Phthalocyanines (Pc) are widely used as catalysts in the process of removal of mercaptans in petroleum refining industries. Conventional separation processes using organic solvents could not be used in the above process as many Pc compounds have intermolecular interactions with macrocycles and the complexes are practically insoluble in these solvents. Considerable efforts have been made to generate new Pc derivatives possessing enhanced solubility characteristics. It has been found that Pc compounds bearing liophilic/hydrophilic substituents on the periphery such as different metals modulate the catalytic activity to a great extent. In the present paper, new Pc catalysts were synthesized [cobalt phthalocyanine tetra-carboxylamide (CoPc(CONH2)4) and cobalt phthalocyanine di-carboxylamide (CoPc(CONH2)2] using facile synthetic route and characterized by C,H,N,MS,UV-Vis and IR. The activity of the generated catalysts could be further compared with the simple un-substituted metal phthalocyanine and some commercial catalysts.
