Detection of the Intermediates in Preparation of Ammonium Polyphosphate by Temperature Raising Rate Factor
Abstract:
Detection of intermediates is the general way to investigate a reaction mechanism, because the intermediates connect the reactants and the products, the intermediates can reflect some internal relationships between the reactants and the products. By studying the the structures of intermediates, the reaction process and reaction mechanism can thus be understood. Ammonium polyphosphate (APP) is an effective material as halogen-free flame retardants, it has six crystalline forms.In preparation of APP, the factor of temperature raising rate is investigated, some intermediates are detected, the XRD spectra of these intermediates are discussed. The results are informative for controllable preparation of APP in industrial production.
