Reactivation of a spent liquid phthalocyanine catalytic composite

摘要

A spent liquid catalytic phthalocyanine composite is reactivated by a method which comprises percolating said spent liquid phthalocyanine composite through a bed comprising an absorbent compound, recovering the percolated liquid catalytic phthalocyanine composite, adding a solid metal phthalocyanine compound to the recovered percolated liquid phthalocyanine composite and recovering the reactivated liquid catalytic phthalocyanine composite for reuse in organic oxidation reactions.
