One-Step Synthesis of Sodium Trimetaphosphate (Na3P3O9) from Sodium Chloride and Orthophosphoric Acid

Abstract : One-step thermal synthesis of sodium trimetaphosphate (STM) from sodium chloride and 85 wt % orthophosphoric acid as starting materials was investigated. The reaction temperature and volume-mean diameter of sodium chloride influenced strongly the elimination of chloride and the selectivity in STM. STM of high quality (99%) was obtained at 600 degrees C from fine powder of sodium chloride. Hydrochloric acid was the only byproduct of the reaction.
