  • Patent number: 6737526
    Abstract: Bis-(pentaerythritol phosphate) phosphoric acid is prepared by mechanochemical synthesis including ball milling a mixture containing P2O5, pentaerythritol, an alkyl benzene having one or two C1-C5 alkyl groups, and a metal halide catalyst, in a ball mill as a reactor and at a temperature of room temperature to 150° C. Melamine is then reacted with the resulting bis-(pentaerythritol phosphate) phosphoric acid to form a product of melamine salt thereof.
