| titleOfInvention | A kind of preparation method of hexaphenoxycyclotriphosphazene |
| abstract | The invention discloses a kind of preparation method of hexaphenoxycyclotriphosphazene, comprise the following steps: 1) phenol and alkali metal hydroxide are dispersed in methyl alcohol, back flow reaction under protection of inert gas; 2) remove methanol solvate and reclaim, by dry after products therefrom cooling; 3) phenates of upper step gained, ketones solvent are placed in reactor, then in reactor, are added dropwise to the ketone solution of hexachlorocyclotriphosphazene; 4) back flow reaction; 5) remove desolventizing after reaction and reclaim; 6) add deionized water to reactor, stir to make product dispersed, material is released centrifugal, repeat to be washed to filtrate in neutral; 7) upper step products therefrom is dried, obtain crude product; 8) by crude product and alcoholic solvent heating, stir, be cooled to less than 25 DEG C, suction filtration obtains product; 9) upper step products therefrom is dried.Technical process of the present invention is simple, and consume energy low, solvent is recyclable, and productive rate is higher, and the purity of products therefrom is also higher. |
