CATALYST AND METHOD OF HOMOGENEOUS OXIDATIVE DEMERCAPTANISATION OF OIL AND OIL PRODUCTS Russian patent published in 2010 - IPC B01J23/745 B01J23/75 C09B47/00 C10G27/10 

FIELD: chemistry.

SUBSTANCE: described is a catalyst for oxidative demercaptanisation of oil and oil products which is a derivative of phthalocyanine, distinguished by that it is a supramolecular ion-associate of oppositely charged phthalocyanines with structural formula I, I:(R⁺)_nPcM, where R=-CH₂N⁺(CH₃)₂CH₂CH₂OHCl^- (chol_n- PcM), n=2÷8, M=Co, Fe; (pym_n-PcM), n=2÷8, M=Co, Fe; (R^-)_nPcM, where R=-CH₂P(=O)(O^-Na⁺)₂(phos_n-PcM), n=8, M-Co and II, II:(R^-)_nPcM, where R=R¹=R²=-C(O)O^-Na⁺ (carb₈-PcM), n=8, M=Co, Fe; R=R¹=-C(O)O^-Na+, R²=H (carb₄-PcM), n=4, M=Co; R= R¹=-S(O)₂O^-Na⁺ , R²=H (sul₄-PcM), n=4, M=Co. Also described is a method of oxidative catalytic demercaptanisation of oil and oil products with atmospheric oxygen in an alkaline medium in the presence of the above described catalyst at room temperature.

EFFECT: carrying out the process in mild conditions with high substrate conversion to 98 percent.
