Uses and synthesis of Polyphosphoric acid Liquid

Polyphosphoric acid CAS 8017-16-1 is produced by the condensation of phosphoric acid (H3PO4) by heating and dehydration. It can also be obtained by adding phosphorus pentoxide to pure water and then condensing with heat. It is colorless and transparent syrupy substance at room temperature. At low temperature, it is solid glassy, and fluidity appears when it is heated to 50~60°C. Polyphosphoric acid Liquid is easily deliquescent, miscible with water and hydrolyzed to phosphoric acid.

The concentration of Polyphosphoric acid Liquid can be expressed in two ways, one is expressed by P2O5%; the other is expressed by the content of H3PO4 in Polyphosphoric acid Raw Materials with H3PO4 as 100%.Polyphosphoric acid CAS 8017- 16-1 The acidity is weaker than nitric acid and sulfuric acid, and has no oxidizing ability. It is hygroscopic and easily deliquescent. It will cause combustion in the presence of H foaming agent.

Polyphosphoric acid Raw Materials is corrosive and is a dipolar inorganic acid corrosive. Polyphosphoric acid Raw Materials is a proton acid, can dissolve a variety of low molecular and macromolecular organic compounds.Polyphosphoric acid Raw Materials is used as a water loss agent, cyclization agent, acylation agent in organic synthesis, and is a catalyst or solvent for the reaction of condensation, cyclization, rearrangement, substitution, etc. Sometimes it is used as a solvent for the reaction of condensation, cyclization, rearrangement and substitution. Sometimes polyphosphoric acid (PPE) is used to increase the solubility of polyphosphoric acid in organic solvents.

In addition, Polyphosphoric acid CAS 8017-16-1 is also used as a substitute for orthophosphoric acid and as an analytical reagent.
