CATALYST FOR OXIDATION OF SULPHUROUS COMPOUNDS Russian patent published in 2014 - IPC B01J31/22 B01J23/24 B01J23/72 B01J23/75 B01J23/755 

FIELD: chemistry.

SUBSTANCE: invention relates to production of heterogenic catalysts for liquid-phase oxidation of sulphurous compounds, namely to catalyst of oxidation of sulphurous compounds on polymer carrier from low pressure polyethylene (LPPE) or polypropylene. Catalyst contains cobalt phthalocyanine and/or its water-insoluble derivative, such as cobalt dichlorophthalocyanine, and oxide of variable-valence metal, namely manganese oxide (IV), and/or copper oxide (II), and/or nickel oxide (II), and/or cobalt oxide (III). Content of components, wt % is the following: cobalt phthalocyanine and/or cobalt dichlorophthalocyanine - 0.05-20.0; manganese oxide (IV), and/or copper oxide (II), and/or cobalt oxide, and/or nickel oxide (II) - 0.05-20.0; LPPE or polypropylene - the remaining part.

EFFECT: invention makes it possible to obtain catalyst with increased activity in oxidation of sulfides and mercaptides and less sensitive to impact of admixtures of organic amines.
