FIELD: chemistry.
SUBSTANCE: invention relates to homogeneous catalysts for oxidation of dialkyldithiocarbamates based on cobalt tetra-4-(1-benzotriazolyl)-tetra-5-(sulphonaphthoxy)phthalocyanines. Phthalocyanine complexes used are complexes of cobalt(II) with tetra-4-(1-benzotriazolyl)-tetra-5-(4-sulpho-1-naphthoxy)phthalocyanine and tetra-4-(1-benzotriazolyl)-tetra-5-(1,6-disulpho-2-naphthoxy)phthalocyanine of formula
Complexes are obtained through sulphonation of isomeric cobalt complexes of tetra-4-(1-benzotriazolyl)-tetra-5-(1-naphthoxy)phthalocyanine and tetra-4-(1-benzotriazolyl)-tetra-5-(2-naphthoxy) phthalocyanine.
EFFECT: invention enables to obtain catalysts based on cobalt tetra-4-(1-benzotriazolyl)-tetra-5-(sulphonaphthoxy)phthalocyanines, having high catalytic activity during oxidation dialkyldithiocarbamates.
