| titleOfInvention | A kind of preparation method of tris (2-allyl) phenoxy triphenoxy cyclotriphosphazene |
| abstract | The present patent discloses a preparation method of tris(2-allyl)phenoxytriphenoxycyclotriphosphazene. Add phenol, 2-allylphenol, strong base, phase-transfer catalyst and toluene successively in the mixture, be warming up to reflux temperature, steam 1 half amount of toluene after water separation, then cool the material to room temperature, and add dropwise hexachlorocyclohexane Triphosphazene toluene solution, dripped for 0.5-1.0h, then heated the material to 70℃-110℃ for 8-15h, then cooled to room temperature, washed twice with a certain amount of 20-40% NaOH solution, and then washed with a certain amount of 20-40% NaOH solution. Wash once with 5-10% hydrochloric acid solution, then wash with deionized water until neutral, and finally steam out toluene to obtain the product. The method has the advantages that the preparation process is simple, the reaction time is short, the consumption of 2-allylphenol and phenol is low, and the three wastes produced are relatively few. |
