The monopatassium salt of 4-sulfophthalic acid and monopotassium salt of 4-sulfophthalonitrile were synthesized and condensed to give tetrapotassium salt of zinc tetra sulfophthalocyanine by the solid fusion method or reaction in an inert solvent in the presence of (NH4)2MoO4, urea, ZnCl2 and NH4Cl. The results showed that the first method gave a better yield (46%). The structures of precursors and the end product were characterized by elemental analysis, IR, 1H NMR and 13C NMR.
