Pyrophosphates may hydrolyze to inorganic phosphoric acid (phosphate) and an organophosphoric acid. [Pg.875]

The quantitative stoichiometry of the D-glucose-chlorous acid reaction has been studied in detail the reagent used was sodium chlorite in a phosphoric acid-phosphate buffer at pH 2.4-3.4. The molar ratio of oxidant consumed to D-glucose consumed was 3 1 no overoxidation occurred over extended periods of time. The method is recommended for the determination of aldehyde groups in carbohydrates, especially alkali-sensitive carbohydrates. [Pg.322]

This very common coordination number usually leads to a tetrahedral configuration for phosphoric acid, phosphates, and many phosphorus(V) compounds. In these compounds, the P(V) atom forms one double bond and three single bonds with other atoms. Figure 15.4.2(e) shows the structure of P4O10, whose symmetry is Td. The length of the terminal P=0 bond is 143 pm, and the bridging P-O bond is 160 pm. The bond angle O-P-O is 102°, and P-O-P is 123°. [Pg.589]

The secondary antioxidants are usually sulfur compounds (mostly thioethers and esters of thiodipropionic acid) or trimesters of phosphorous acid (phosphates). A remedy for many types of discoloration in plastics is often the use of a phosphite or a thioether. Both have the ability to react with hydroperoxides, as those formed in Reaction 1.72, to yield noruadical products, following heterolytic mechanisms. The reaction of phosphites to phosphates as an example ... [Pg.103]

The effect of acid concentration on polarization of active-passive metals is shown in Fig. 4.8. Higher hydrogen ion concentration increases the critical anodic current density and decreases the passive potential range. Severe corrosion conditions present at higher acidity also increase current densities and corrosion rates at all potentials. Figure 4.9 presents the data for iron passivation in phosphoric acid/phosphate buffer solutions of... [Pg.155]

Cellulose sulfates and phosphates are water-soluble derivatives prepared by reactions of alcohol/water/organic diluent mixtures of sulfuric or phosphoric acids. Phosphate derivatives are flame retardant but have not been commercialized (72). [Pg.9184]

Phosphate Bond. Cold-setting bonds for refractories can be formed by reactions between oxides and phosphoric acid, phosphate-phosphoric acid reactions or the direct use of liquid phosphate bonds. The bond is due to the formation of an acid phosphate, with weakly basic or amphoteric oxides. [Pg.231]
