Chromatographic
separation of constitutional M.I. isomers of octasubstituted
phthalocyaninatocopper (II)
Abstract
The
chromatographic behaviour of
tetra-4-nitro-tetra-5-phenoxyphthalocyaninatocopper is studied under the
conditions of normal-phase and reversed-phase high-performance liquid
chromatography (HPLC). It is demonstrated that this compound and the series of
the similar octasubstituted phthalocyanines contain the constitutional isomers
for which separation is the most suitable the hexane - toluene (20:80) -
Silasorb 600 (150x3,9-mm column)
system. The chromatographic properties
of copper (II) complexes with tetra-4-nitro-tetra-5-phenoxyphthalocyanine and
tetra-4-tert-butylphthalocyanine are compared.
