| Abstract: | The properties, synthesis process and application of aluminium dihydrogen tripolyphosphate are presented. The substitute of purified wetprocess phosphoric acid for thermalprocess phosphoric acid is considered an advancement as lower cost. The FineChemical Team, Kunming University of Science and Technology, adds some purifying agents into the solution of fertilizergrade monoammonium phosphate, and makes it conform to the necessity of aluminium dihydrogen tripolyphosphate synthesis. The synthesis is promising to be an ideal approach replacing the traditional thermalprocess. |
