Descrizione

For synthesis

Polyphosphoric acid (PPA) is a strong mineral acid that combines orthophosphoric acid and linear phosphoric acids. It is widely used in organic synthesis because of its powerful dehydrating properties, low nucleophilicity of the phosphoric acid media, good solvation power, relatively mild acidity, and low oxidation potential. Even though PPA is a significantly weaker acid than H2SO4, it demonstrates 100% dehydration rate.
