Detection of the Intermediate in Preparation of Ammonium Polyphosphate by Temperature Factor

Abstract:

Ammonium polyphosphate (APP) is a long chain polyphosphate salt, it has six crystalline forms. In preparation of APP, temperature is significant to controllably obtain a certain crystalline forms. In this paper, the effect of temperature is investigated during the preparation process of APP. Some intermediates are detected, the XRD spectra of these intermediates are discussed. The results show that temperature at 2800C is suitable for preparation of form II. With temperature increasing, water insolubility increases. The results are informative for controllable preparation of APP in industrial production.
