A method for preparing a melamine salt of pentaerypolyol phosphoric acid is provided. The method comprises the following steps of: ball milling a mixture of pentaerypolyol and phosphorus pentoxide (PO) under a solvent-free reacting environment to obtain a pentaerypolyol phosphoric acid, and ball milling a mixture of a pentaerypolyol phosphoric acid and melamine without organic solvent reacting environment to obtain a melamine salt of pentaerypolyol phosphoric acid.

Mechanochemical synthesis of pentaerythritol phosphate alcohol is disclosed. The synthesis is carried out by ball milling a mixture containing P O , 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&deg; C.

Method for preparing pentaerythritol phosphate alcohol by mechanochemical synthesis

Bis-(pentaerythritol phosphate) phosphoric acid is prepared by mechanochemical synthesis including ball milling a mixture containing P O , 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&deg; C. Melamine is then reacted with the resulting bis-(pentaerythritol phosphate) phosphoric acid to form a product of melamine salt thereof.
