Phosphoric acid
Liquid phosphoric acid Introduction:
Food and Nutrition - Food-grade phosphoric acid (additive E338[18]) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. Soft drinks containing phosphoric acid, which would include Coca-Cola, are sometimes called phosphate sodas or phosphate.

Liquid phosphoric acid Applications:
Commonly used as analytical reagent
For capacity and colorimetric analysis
In the production of silicon planar tubes and integrated circuits, aluminum film is commonly used as electrode lead, and it is necessary to photolithograph the aluminum film and use phosphoric acid as acid cleaning etchant. It can be used with acetic acid.
The pharmaceutical industry is used to manufacture sodium glycerophosphate, iron phosphate, etc., as well as zinc phosphate as a dental filling adhesive. It is used as a catalyst for the condensation of phenolic resin, a drying agent for the production of dyes and intermediates. The printing industry is used to prepare the cleaning solution for wiping off the stains on the offset color printing plate. It is also used to prepare match stem maceration solution. The metallurgical industry is used to produce phosphoric acid refractory mud and improve the service life of steelmaking furnace. It is the coagulant of rubber slurry and the raw material for producing inorganic binder. The paint industry is used as metal antirust paint.
It can be used as yeast nutrient, chelating agent, antioxidant synergist and inorganic acid flavor agent, with the acidity of 2.3~2.5. It can be used for compound condiments, cans, cheese, jelly and cola drinks, and can be used appropriately according to production needs.
Mainly used as catalyst for ethylene hydration to produce ethanol, high-purity phosphate, pharmaceutical manufacturing, and chemical reagent.
Determination of chromium, nickel and vanadium in iron and steel, metal rust prevention, rubber coagulant, determination of non protein nitrogen in serum, total cholesterol and glucose in whole blood. Crystalline phosphoric acid is mainly used in microelectronics, high-energy batteries, laser glass and other manufacturing processes, as well as high-purity catalysts and medical materials.
