FIELD: chemistry. ^ SUBSTANCE: invention relates to self-organising supramolecular ion-associates of oppositely charged phthalocyanines and their use for oxidising sodium sulphide. A catalyst for oxidising sodium sulphide is described, where the said catalyst is a phthalocyanine derivative and is 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- (choln- PcM), n=28, M=Co, Fe; (pymn-PcM), n=28, M=Co, Fe; (R-)nPcM, where R=-CH2P(=O)(O-Na+)2(phosn-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 oxidising sodium sulphide with oxygen in the presence of the above described catalyst. ^ EFFECT: achieved complete substrate conversion corresponding to activity 3.1x103 mol(Na2S)/mol (catalyst) min. ^ 3 cl, 2 tbl, 44 ex |
