FIELD: chemistry.
SUBSTANCE: claimed is a method of preparing a heterogeneous phthalocyanine catalyst for oxidation of sulphur-containing compounds by an activation of non-woven lavsan by microwave radiation with a frequency of 2450 MHz, power 500-2000 W for 3-15 minutes, processing the activated material in a solution of cobalt tetra-4-[(4'-carboxy)phenylsulpfanyl]phthalocyanine with a concentration of 0.2-0.6 g/l for 2-4 hours and further stand of the material in a sodium hydroxide solution at pH 8.0-8.5 for 40-80 minutes.
EFFECT: increased catalytic activity of the target product and simplification of the method of its preparation.
