Phosphoric Acid Powder Usage and Synthesis.

Phosphoric acid is a colorless rhombohedral crystals, viscous liquid, density of 1.834g/cm3, melting point of 42.35 ℃, to the boiling point of 213 ℃ (loss of ½ H2O) to generate pyrophosphoric acid, heated to 300 ℃ into metaphosphoric acid. The acidity of phosphoric acid is between strong acid and weak acid, weaker than sulfuric acid, hydrochloric acid and nitric acid and other strong acids, but stronger than acetic acid, boric acid and so on.

Commercially available phosphoric acid is a thick liquid containing 83%-98% H3PO4. Phosphoric acid has a wide range of applications in electric vehicles, energy storage systems, portable electronic devices and wearable devices.

Uses of Phosphoric Acid.

Wet process phosphoric acid is mainly used for the manufacture of various phosphates, such as ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, etc. and condensed phosphates. Refined phosphoric acid is used to make calcium phosphate for feed. Used for metal surface phosphating treatment, formulated electrolytic polishing solution and chemical polishing solution for polishing aluminum products.

Pharmaceutical industry for the manufacture of sodium glycerophosphate, iron phosphate, etc., but also for the manufacture of zinc phosphate as dental fillings adhesive. Used as a catalyst for phenolic resin condensation, dyes and intermediates production of desiccant. Printing industry for the preparation of wipe offset color printing plate stains on the cleaning solution.

It is also used to formulate impregnating liquid for matchsticks. Metallurgical industry for the production of phosphoric acid refractory mud, improve the life of steelmaking furnace. It is the solidifying agent of rubber paste and the raw material for producing inorganic binder. Used in paint industry as antirust paint for metal.

Determination of chromium, nickel, vanadium composition in steel, metal rust prevention, rubber coagulant, determination of non-protein nitrogen in serum, total cholesterol and whole blood glucose and so on. Crystallized phosphoric acid is mainly used in microelectronics, high-energy batteries, laser glass and other manufacturing processes, as a high-purity catalyst, medical materials.

It can be used as acidifier and yeast nutrient. It can be used as souring agent for seasoning, canned food and refreshing drinks. Used as yeast nutrient source in brewing to prevent the propagation of stray bacteria.

Pharmacological effect of Phosphoric Acid.

Product Method of Bulk Phosphoric Acid Powder.

The precipitant barium hydroxide is slowly added to the sulfur reduction tank containing crude phosphoric acid, stirred and heated to 95 ℃, and maintained for 20min after being put into the aging tank, aging for about 26d. The lower turbid liquid is filtered to recover phosphoric acid, and the upper clear liquid is heated to 85 ℃ and pumped to the top of the arsenic removal filling tower, and H2S gas is passed from the bottom of the tower.

Excess tail gas from the top of the tower into the NaOH solution neutralization tank, with suspended blocks of phosphoric acid slurry from the bottom of the tower out of the material into the cohesion tank, and heated to 90 ℃, and then through the filtration tank, adjusting the tank (maintaining the temperature of 80 ℃), and then into the adsorption tank. The temperature of the adsorption tank is controlled at 80 ℃, add activated carbon, diatomaceous earth stirring adsorption for 1 h. Finally, it enters the filtration slurry tank, and is filtered at 55 ℃ to obtain food grade phosphoric acid.
