Effect of Wet Ammonia on Crystalline Forms of Ammonium Polyphosphate

Abstract:

Ammonium polyphosphate (APP) has six crystalline forms, in which form II is commercially applied as flame retardant in engineering plastics such as PP and ABS, form V is extensively studied recently. In preparation of APP, the reaction atmosphere is significant to controllably obtain a certain crystalline forms. In this paper, the effect of wet ammonia is investigated. The results show that low concentration of wet ammonia is suitable for preparation of form II, while dry ammonia is suitable for preparation of form V. The results are informative for controllable preparation of APP in industrial production.
