DESCRIPTION
General description
Phosphoric acid (H3PO4) is also known as orthophosphoric acid. It serves as an intermediary or reagent in various manufacturing processes. Phosphoric acid is found in fertilizers, detergents, and other household cleaning products. The product is crystalline phosphoric acid.
Application
Phosphoric acid has been employed as an oxidation reagent in a study.1 It may be used in the preparation of ammonium phosphate.[1] Phosphoric acid is used:
As a catalyst in the nucleophilic addition to imines.
In the synthesis of porous phosphoric acid-based geopolymers.
In the synthesis of mono-alkyl phosphates from simple aliphatic alcohols in the presence of acetic anhydride activator.
Packaging
100, 500 g in glass bottle
1 kg in glass bottle
Other Notes
Concentrated phosphoric acid is approx. 85% H3PO4 (aqueous).
Caution
product may become solid, becomes liquid on heating to 50°C
