Procedure
3780 g melamine (30 mol.) are mixed with 2130 g (15 mol.) phosphorus pentoxide in a laboratory ploughshare mixer with an effective volume of 10 l and thermal oil-heated double jacket and heated to a temperature of 200° C. Within 30 min, 630 g (5 mol.) oxalic dihydrate are then added. After a secondary reaction time of a further 15 min, the melamine polyphosphate formed was removed from the mixer.
