APPLICATIONS

Organic Synthesis

Poly phosphoric acid is used in the synthesis of aromatic sulfones, N-substituted amides and 4-aminobenzophenones. It is also used in dehydration, Fischer-Indole Synthesis, Beckmann Rearrangement and Schmidt Rearrangement reactions.

Catalyst

It can be used as a catalyst in the synthesis of various aromatic ketones. PPA is used as a catalyst during the synthesis of dimethyl carbonate (DMC) from urea and methanol.

Other

It also acts as an absorbent for the ammonia generated in the process. PPA is used to prepare silica-supported poly phosphoric acid (PPA-SiO2), an easy to handle reusable heterogeneous catalyst.
