概要

Polyphosphoric acid (PPA) is widely employed as acylation and alkylation reagent in various reactions. It is a strong mineral acid with excellent dehydrating properties.

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-SiO 2 ), an easy to handle, reusable heterogenous catalyst.

よくある質問

What does Reagent Grade mean?

Reagent Grade is a defined analytical purity tier suitable for general analytical and reagent applications. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Reagent Grade is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.

How should this product be stored?

Store at room temperature under argon. It is supplied under an argon blanket; reseal under inert gas after each use.
