Published: Apr 07, 2021 Polyphosphoric Acid (PPA) Market: Introduction Polyphosphoric acids (PPA) are reactive oligomers having a short-chain polymer. These inorganic chemicals are odorless, colorless, highly viscous liquids and possess strong hygroscopic properties. Phosphorus pentoxide (P 2O 3PO 4) are two basic compounds used in the production of polyphosphoric acid (PPA). Its preparation procedure includes heating and dehydration of phosphoric acid followed by a polycondensation process. Polyphosphoric acid (PPA) is available in various grades in the market. Polyphosphoric acids (PPA) are utilized in a wide variety of reagent applications in the chemical industry. These powerful dehydrating agents for organic synthesis, and intermediate for the production of phosphate esters with high mono-ester content. As a catalyst, polyphosphoric acid (PPA) is employed in petroleum and petrochemical for several processes such as dehydration, polymerization, alkylation, isomerization processes, and condensation. These compounds are also used in the metal treatment and as an asphalt and bitumen additive.
