polyphosphoric acid
Packing : In 40kg blum plastic drum or 340kg plastic drum or 1.7MT IBC.
Properties: Clear colorless viscous liquid, deliquescent, soluble in water with hydrolysis to phosphoric acid.
Use: Polyphosphoric acid is not only an important intermediate product, it is also an important chemical product. It widely used in such as pigment, pharmacy, spice, fire retardant manufacturing, detergent, skin care products, cosmetics industries. In organic synthesis, it used as cyclizing agent, acidulating agent and dehydrating agent and so on. It also can be used as substitutes for orthorphosphoric acid.
PPA is widely used in industries including medicine, aromatics, leather, chemical industry, etc.. It is used as cyclizing agent, acidifier and dehydrant in organic synthesis. It can also be used as the substitute for orthophosphoric acid.
PPA can be used as a catalyst in the chemical and the petroleum industries for polymerization,alkylation, dehydration, condensation, and isomerization processes
