General description
Application
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.
