Application
Polyphosphoric acid may be used in the synthesis of aromatic sulfones, N-substituted amides and 4-aminobenzophenones. It may also be used in dehydration, Fischer-Indole Synthesis, Beckmann Rearrangement and Schmidt Rearrangement reactions. It can be used as a catalyst in the synthesis of various aromatic ketones.PPA may be used as a catalyst during the synthesis of dimethyl carbonate (DMC) from urea and methanol. It also acts as an absorbent for the ammonia generated in the process. PPA may be used to prepare silica-supported polyphosphoric acid (PPA-SiO2), an easy to handle, reusable heterogenous catalyst.
General description
Polyphosphoric acid (PPA) is widely employed as acylation and alkylation reagent in various reactions. It is a strong mineral acid with excellent dehydrating properties.
