| Abstract: | The process conditions is studied for preparation of ammonium polyphosphate with chelates containing Cu or Fe based on water soluble ammonium polyphosphate and copper sulfate, ferric nitrate as raw materials. The results show that the optimum chelating conditions are pH of 7.0, the reaction temperature of 35 ℃ （and 40 ℃ for Fe^3＋） , the reaction time of 60 min. The solubility values of two chelates are measured, and the two chelates are confirmed with the raman spectroscopy and the infrared spectroscopy. |
