  • Process for the preparation of polyphosphates of organic bases
    Patent number: 7893142
    Abstract: A simple and economical process for the preparation of polyphosphates of organic bases consists of reacting a mixture of phosphorus pentoxide and at least one organic nitrogen base with at least one compound which releases water accompanied by decomposition under the prevailing conditions in such a molar ratio that upon decomposition of the water-releasing compound at most essentially 2 mol. water are produced per mol. phosphorus pentoxide. Thus-prepared polyphosphates are particularly suitable as flame-protection agents for plastics.
    Type: Grant
    Filed: December 7, 2007
    Date of Patent: February 22, 2011
    Assignee: Chemische Fabrik Budenheim KG
    Inventors: Karl Gotzmann, Liselotte Götzmann, legal representative, Hans-Dieter Nägerl, Thomas Futterer
