Tetrapolyphosphoric acid

The dehydration reaction (elimination of H2O) between phosphoric acid (H3PO4) and diphosphoric acid (H4P2O7) results in the molecule H5P3O10 or tripolyphosphoric acid. A further dehydration reaction with phosphoric acid results in the formation of H6P4O13 or tetrapolyphosphoric acid. [Pg.264]

Cellulose Phosphates. There are a number of strategies for preparing cellulose phosphate. Reaction of cellulose with tetrapolyphosphoric acid in the presence of triethylamine produced cellulose phosphate with DSp < 1.75 (29). Treatment of cellulose with POCI3 resulted in cellulose phosphate with low DSp, but also resulted in introduction of chloride to the cellulosic backbone (Table 6) (30). Phosphorylations of cellulose with A(-phosphoryl-A( -methylimidazole and a... [Pg.1085]
