Paragraph 0016-0017; 0022-0023; 0024; 0025-0026, (2018/03/25)
The invention discloses a preparation method of pentafluoro aromatic oxyl cyclotriphosphazene. The preparation method comprises: (1) adding hexachlorocyclotriphosphazene, a fluorinating agent and an organic solvent to a reaction container, and carrying out a reaction at a temperature of -30-80 DEG C to obtain a hexachlorocyclotriphosphazene-containing reaction liquid; (2) carrying out water washing on the reaction liquid obtained in the step (1), carrying out standing liquid layering to obtain a hexachlorocyclotriphosphazene-containing ogranic phase, and distilling the organic phase to obtainhexachlorocyclotriphosphazene; (3) adding an organic solvent, a phenol, an acid binder and the hexafluorocyclotriphosphazene obtained in the step (2) to another reaction container, and carrying out areaction at a temperature of -30-80 DEG C to obtain a reaction liquid containing pentafluoro aromatic oxyl cyclotriphosphazene; and (4) carrying out rectification on the reaction liquid obtained in the step (3) to obtain the pentafluoro aromatic oxyl cyclotriphosphazene. The preparation method of the present invention has advantages of less side reactions and high yield, and is suitable for industrial large-scale production, wherein the yield is not less than 60%.
