  • Method for preparing pentaerythritol phosphate alcohol by mechanochemical synthesis
    Patent number: 6833467
    Abstract: Mechanochemical synthesis of pentaerythritol phosphate alcohol is disclosed. The synthesis is carried out by 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 70-150° C.
    Type: Grant
    Filed: November 12, 2002
    Date of Patent: December 21, 2004
    Assignee: Chung-Shan Institute of Science & Technology
    Inventors: Chong Ma, Wen-Yo Chen, Yuen-Hsin Peng
  • Method for preparing melamine salt of bis-(pentaerythritol phosphate) phosphoric acid
    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.
    Type: Grant
