| titleOfInvention | Process for the preparation of ammonium polyphosphate yelding a low viscous aqueous suspension |
| abstract | A process for producing essentially water-insoluble, chain-type ammonium polyphosphates of the general formula (NH4PO3)n, in which n is a number from 10 to 1,000, whose 20% by weight aqueous suspension prepared at 60 DEG C. has a viscosity of less than 100 mPa.s at 20 DEG C., is indicated, which comprises allowing a reaction mixture of ammonium orthophosphate and phosphorus pentoxide to react fully at a high mixing intensity in a crumbly phase at a temperature from 100 DEG to 300 DEG C. over a period of from 10 to 60 minutes and then heat-treating the reaction material in a known manner over a period of from 50 to 200 minutes at a temperature from 200 DEG to 300 DEG C. under an ammonia atmosphere. Advantageously, the reaction is carried out in a kneader. |
