| titleOfInvention | Method of synthesis of hexafluorobenzene or its mono- or disubstituted derivatives |
| abstract | FIELD: chemical technology. SUBSTANCE: invention relates to chemical technology of polyfluoroarenes, in part, synthesis of hexafluorobenzene or its mono- or disubstituted derivatives of the formula C 6 F 4 -XY where: X - F, Cl, H, CF 3 , CCl 3 ; Y - F, CN, H, Cl, CF 3 , CCl 3 . These derivatives were synthesized by chlorine substitution in the corresponding polychloroarenes with potassium fluorofluoride without solvent at heating to 150-250 C in the presence of catalytic system quaternary phosphonium salt/water at mole ratio of components = (1:0.5)-(1:50) and mole ratio potassium fluoride and quaternary phosphonium salt = (200:1)-(10:1). The yield of the end product is up to 98.7%. Synthesized compounds were used for synthesis of dyes, drugs, monomers. EFFECT: improved method of synthesis, increased yield. 5 cl |
