Phosphoric acid

Phosphoric Acid (H3PO4) is a colorless, odorless phosphorus containing inorganic acid and it is one of the most produced acids in the world. Phosphoric acid, as an important industrial chemical, serving as the basis for all the phosphorus compounds in phosphorus industry. Since the 1970s, wet process has been widely used to produce 3PO4 , which is based on the attack of large amounts of concentrated acid on apatite ores at a certain temperature. Sulfuric acid (2SO4). The most commonly used acid is the wet process and is separated from the phosphoric acid by filtration. Phosphate rock is mainly used in the production of phosphoric acid and superphosphoric acid in the United States. These middle products are primarily used in fertilizer production.

Element phosphorus is a growth limiting nutrient greatly required by almost all the living organisms and various phosphoric compounds play important roles in agricultural, industrial, medical, food manufacturing and environmental processes

In the past decade, the production of phosphoric acid has grown dramatically. This family has been one of the strongest organic catalysts. New generations of phosphoric acid chiral acids are available for catalyzing a wide range.


Applications of Phosphoric acid 

The common acid “debility” is very marked in this remedy, producing a nervous exhaustion. A congenial soil for the action of phosphoric acid is found in young people who grow rapidly, and who are overtaxed, mentally or physically. Whenever the system has been exposed to the ravages of acute disease, excesses, grief, loss of vital fluids, we obtain conditions calling for it. Pyrosis, flatulence, diarrhea, diabetes, rhachitis and periosteal inflammation. Neurosis in stump, after amputation. Hemorrhages in typhoid. Useful in relieving pain of cancer. In dentistry, it may be used in silicate cements, and to etch enamel and dentin surfaces prior to application of various types of resins. In may also be used as a dispersing agent in pharmaceuticals

The primary use of phosphoric acid is in fertilizers. Fertilizers provide a range of nutrients to support plant growth the principle macronutrients are nitrogen(N), phosphor(P), and potassium(K); other important are Aluminum, calcium, magnesium and sulfur.

Water treatment
In the petrochemical industry, food industry, agriculture, and in general industries whose output is high purification water BOD(biological oxygen demand), it is used to reduce water biologically, bacteria that are used in this method, In order to function correctly, they need nutrients (P) as well as favorable pH conditions. In the absence of any of these conditions, the following products can be used as a source of phosphorus (alone or in combination): pure phosphoric acid, mono ammonium phosphate (MAP), Diammonium phosphate (DAP), and monopotassium phosphate ( MKP).

For many years, our researchers have been developing various products for use in water treatment. On account of their special properties, phosphates and purified phosphoric acid help to reduce the risk of pipework corroding, prevent the deposit of lime scale, control the pH of water.

  • pH control pH

Another vital parameter in water treatment is controlling the pH of the water. The pH is the concentration of H+ +ions in a water solution, varying from 0 (acid) to 14 (alkaline), pH 7 is neutral. Due to the buffer capacity (pH adjustment), orthophosphates and pure phosphoric acid can maintain water pH levels as much as possible.

  • Lead precipitation agent

Some older buildings still have their original lead piping. The presence of lead (Pb) in the water can be harmful to human health. In order to avoid dangerously high lead content in water from the system, a small amount of purified phosphoric acid can be added to encourage a coating to form on the inner surface of the lead pipes, thereby preventing the lead from being released into the water

Food industry
Phosphoric acid is a common oral supplement by decreasing bone mineral density. A nonsense is used in foods and beverages. The main source of phosphoric acid is soda. The cause of the sharp flavor is phosphoric acid.
Very diluted phosphoric acid coupled to moderate heating below 90°C to partial hydrolysis of polysaccharides from different phytobiomass sources is feasible and advantageous.

Other usage:

Iron oxide removal
Detergents: Such as three sodium phosphate and sodium tripolyphosphate
The production of animal feed and poultry supplements, such as di-calcium phosphate
Production of flame retardant materials for firefighting purposes
Production of industrial phosphate cleanser
Water treatment
Food industry
