Description

Description générale

meta-Phosphoric acid is a polymer form of phosphoric acid. It is used as a catalyst as well as a reactant in chemical synthesis.

Application

meta-Phosphoric acid can be used as:      

• A catalyst in combination with InCl₃ to synthesize 1,8-dioxooctahydroxanthene derivatives by the reaction of cyclic β-diketones and aldehydes.      
• A phosphate precursor to synthesize antimony phosphate (SbPO₄) by reacting with antimony metal at high temperatures.
