Detection of the intermediate in Preparation of Ammonium Polyphosphate by Ammoniating Rate Factor
Ammonia atmosphere is significant to eontrollably obtain a certain crystalline forms.In this paper,the effect of ammoniating rate is investigated.Some intermediates are detected during the preparation process of APP,the XRD spectra of these intermediates are discussed.The results show that low ammoniating rate is suitable for preparation of APP form Ⅱ.With ammoniating rate increasing,most of the crystals transform to APP V in the intermediate and water insolubility of the product increases.The results are informative for controllable preparation of APP in industrial production.
