Federal Register :: Phosphoric Acid Manufacturing and ...

The basic step for producing phosphoric acid is acidulation of phosphate rock. Typically, sulfuric acid, phosphate rock, and water are combined together and allowed to react to produce phosphoric acid and gypsum. When phosphate rock is acidulated to manufacture wetprocess phosphoric acid (WPPA), fluorine contained in the rock is released.

Brief review of the chemistry of polyphosphoric acid (PPA ...

The basic compounds for the production of polyphosphoric acid (PPA) are phosphorus pentoxide (P2O5) and phosphoric acid (H3PO4), as shown in Figure 2. Phosphorus is first oxidized to phosphorus pentoxide, which crystallizes as P4O10. Upon its reaction with water, phosphoric acid is produced. This route to H3PO4 is known as the dry process,

CYCLOHEXENE FROM CYCLOHEXANOL AN E1 REACTION

Phosphoric acid is used instead of other common strong acids for two major reasons: ‾ (a) the anion of phosphoric acid (H 2 PO 4) is a poor nucleophile, so the tendency toward substitution is minimized, favoring elimination; and (b) sulfuric acid, normally a logical choice as a strong acid, favors polymerization and degradation of the alcohol.
