RP-HPLC OF SOME METAL PHTHALOCYANINES

The retention parameters of phthalocyanine, tetra-4-t-butylphthalocyan ine and the latter's complexes with zinc, copper, rhodium and lutetium , as well as the copper complex of tetra-4-t-butyltetrabenzotriazaporp hyrin were determined with mu Bondapak C-18 sorbent. It is shown that retention depends on azasubstitution, introduction of aliphatic substi tuents in the macrocycle, the number of macrocycles in molecules and t he nature of the central metal ion in conditions of reversed-phase sys tem. The ligand and complex peaks are symmetrical and they can be used for qualitative and quantitative estimation of the phthalocyanines co ntents in raw products of the synthesis and in the purified material.
