| titleOfInvention | Process for the manufacture of brominated, alkoxy substituted metal phthalocyanine |
| abstract | Process for the preparation of a position isomer mixture of brominated tetraalkoxymetal phthalocyanines of the formula I, where Me stands for Cu (II), Pd (II), Zn (II), Sn (II), Ni (II), Co (II), Pb (II), Mn (O) or V (O), x represents a number from 1 to 5, and R₁ to R₄ are independently linear or branched C₁-C₁₆ alkyl, C₃-C₁₆ alkenyl or C₃-C₁₆ alkynyl radicals which are unsubstituted or with C₁-C₁₂ alkoxy, -CN, NO₂, halogen, -OH, phenyl , Cyanophenyl, nitrophenyl, halophenyl, hydroxyphenyl or (C₁-C₁₂-alkoxy) phenyl are substituted, by reacting a tetraalkoxy metal phthalocyanine of the formula II with bromine, characterized in that the reaction is carried out in a substantially water-immiscible halogenated aromatic solvent in the presence of a second aqueous phase.n n n Substituted phthalocyanines represent an important class of dyes for optical information recording, since with appropriate peripheral substitution, depending on the central metal atom, they have high NIR absorptions in the range from 700 nm to 900 nm. |
