Description

Orthophosphoric acid 75% (food grade)

Orthophosphoric acid, or also called phosphoric acid, is an inorganic acid that, under standard conditions, appears as colorless, hygroscopic crystals. At temperatures above 213 °C, orthophosphoric acid is converted into pyrophosphoric acid H4P2O7. Very soluble in water. Orthophosphoric (or simply phosphoric) acid is often called a 75% aqueous solution (a colorless, odorless, syrupy liquid). Phosphoric acid is also soluble in ethanol and other solvents.

Receipt

In industry, orthophosphoric acid (Phosphoric acid, o-phosphoric acid) is obtained by extraction (sulfuric acid) or thermal methods. The extraction method involves the decomposition of natural phosphates with sulfuric and phosphoric acids and subsequent separation of the resulting acid and insoluble CaSO4 on filters. The thermal method is based on the combustion of phosphorus to phosphorus anhydride P4O10 and hydration of the latter P4O10 + 6H2O = 4H3PO4.

Application of phosphoric acid

Food grade orthophosphoric acid is the most important intermediate product for the production of phosphorus and complex fertilizers and technical phosphates; it is also widely used for the phosphating of metals and as a catalyst in organic synthesis.

  • Food grade phosphoric acid is used to prepare soft drinks, medicines, etc. Phosphoric acid is registered as a food additive E338. Used as an acidity regulator in carbonated drinks, such as Coca-Cola.
  • Orthophosphoric acid is used in soldering as a flux (on oxidized copper, on ferrous metal, on stainless steel), for research in the field of molecular biology. It is also used to clean rust from metal surfaces. Forms a protective film on the treated surface, preventing further corrosion. It is also used in the composition of freons, in industrial freezing units as a binder.
  • Phosphoric acid is used in the aviation industry as part of hydraulic fluids.
  • This acid is also used in agriculture – for example, in fur farming (in particular, when raising minks), drinking a solution of orthophosphoric acid is used to prevent increased stomach pH and urolithiasis.
  • Orthophosphoric acid is very widely used in dentistry – for etching enamel and dentin before filling teeth, in the manufacture of dental cements.
