Reaction Conditions

Reaction Steps

To an one liter four-inlet flask equipped with a thermocouple and temperature controller, a reflux condenser, a nitrogen feed and a mechanical stirrer, 1 mole (86 g) dicyandiamide (DICY) was added, heated to 120° C. and then stirred to a molten state. 1 mole (234 g) diphenyl phosphite (DPP) was added slowly to the molten DICY, and the resulting mixture was heated gradually to a temperature of 190° C. when the addition of DPP was completed. The addition reaction was continued for 4 hours. The reaction mixture was cooled to obtain DPP-DICY (P-12). Yield, 96%; softening temperature, 134-138° C. Phosphorus content: 9.68%. Nitrogen content: 17.50%.
