Melamine → 1,3,5-Triazine-2,4,6-triamine monophosphate

Participants

Reaction Steps

Under atmosphere, charged in a twin-screw extruder were 70.97 g (0.5 moles) of diphosphorus pentoxide and 126.06 g (1.0 moles) of melamine (commercial name: Chang Chun Melamine), and a bar like product was formed at the extrusion temperature of 340° C. After being cooled, the bar like product is pulverized, thereby a powdery melamine phosphate product is obtained. The thermal degradation of the powdery product at 260° C. was measured with differential thermo/thermogravimetric analyzer. The loss of weight was 0.25% by weight. The results of phosphorus content and dispersibility of the powdery melamine phosphate product were shown as in Table 1.
