Zusammenfassung: | FIELD: chemistry of organophosphorus compounds, chemical technology. ^ SUBSTANCE: invention relates to fluorinated phosphoric acids of the general formula: [RyPF6-y]-H+ [I] wherein y = 1, 2 or 3; ligands R are similar and R represents perfluorinated (C1-C8)-alkyl or aryl group or partially fluorinated (C1-C8)-alkyl or aryl group wherein some atoms F and H can be replaced for chlorine atom. Also, invention relates to a method for synthesis of above described acids by interaction perfluoroalkylphosphorane with fluorohydrogen in the presence of suitable solvent and/or proton acceptor, to salts comprising cation and anion of above described acid, and to a method for synthesis of salts. Acids of the formula [I] can be easily synthesized and show high proton activity and stable at room temperature in highly concentrated solution. ^ EFFECT: improved method of synthesis, improved and valuable properties of acids. ^ 18 cl, 33 ex |
