General description

Anhydrous phosphoric acid is a white solid which melts at 42.35oC to form a viscous liquid. In aqueous solution phosphoric acid behaves as a triprotic acid, having three ionizable hydrogen atoms.
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application

Industrially, phosphoric acid may be used in pharmaceuticals, water softeners.

Packaging

Packaged in poly bottles

Other Notes

L′acide phosphorique concentré est composé de H3PO4 à environ 85 % (aqueux).

A highly enantioselective hydroamination/N-sulfonyliminium cyclization cascade is reported using a combination of gold(I) and chiral phosphoric acid catalysts. An initial 5-exo-dig hydroamination and a subsequent phosphoric acid catalyzed cyclization process provide access to complex sulfonamide scaffolds in excellent yield and
