Industrial application

Phthalic anhydride catalyst

The use of vanadium pentoxide as the catalyst in phthalic anhydride manufacture. Named by the producer on the data sheets for its HIGH PURITY grades and not on the data sheet for its chemically pure grade — which is the issuer saying that this use turns on the grade, not on the compound.

The producer names phthalic anhydride catalysis as a use of its HIGH PURITY grades, both ground and unground, and not of its chemically pure grade. The application follows the grade, not the compound.
