Embodiment 1

[0094] Put 1mol of hexachlorocyclotriphosphazene, 200mL of acetone, and 5mol of sodium methoxide into a three-port 2000mL glass reactor with a stirring device. While stirring, nitrogen is blown at the same time, the temperature is raised to 60°C, and 20% sodium hydroxide solution is added dropwise over 60 minutes to The pH value is neutral, keep the temperature at 60°C, stir and react for 8 hours, then add 1mol 3-hydroxypropionaldehyde, continue to stir and react for 5h, then cool down to room temperature, keep the pH of the solution at 9, add dropwise for 60min After the reaction, raise the temperature to 60°C, add hydrochloric acid to adjust the pH to 5, and react for 2 hours. After the reaction, use physical methods to remove the inorganic components and water in the system, distill off the solvent in the system, and use methanol precipitation to obtain the phosphazene with the following structure Compound:
