Description

Phosphoric acid appears as a clear colorless liquid or transparent crystalline solid. Itis a weak acid with the chemical formula H3PO4.
It is a phosphorus oxoacid that consist of one Oxo and three hydroxy groups joined covalently to a central phosphorus atom. It has a role as a solvent, a human metabolite, an algal metabolite, and a fertilizer. It is the conjugate acid of a dihydrogen phosphate and a phosphate ion. H3PO4 also known as orthophosphoric acid or phosphoric (V) acid) is a mineral inorganic acid.it is colorless, odorless phosphorus-containing inorganic acid and it is one of the most produced acids in the world. , as an important industrial chemical, serving as the basis for all the phosphorus compounds in phosphorus industry. Since the 1970s, the wet process has been widely used to produce H3PO4, which is based on the attack of large amounts of concentrated acid on apatite ores at a certain temperature. It can be manufactured using either a thermal or a wet process. However, the majority of this product is produced using the wet-process method. Wet-process this product is used for fertilizer production. The thermal process of this substance is commonly used in the manufacture of high-grade chemicals, which require a much higher purity. The most commonly used acid is the wet process and is separated from the H3PO4 by filtration. 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 this substance has grown dramatically. This family has been one of the strongest organic catalysts. New generations of H3PO4 chiral acids are available for catalyzing a wide range.

Physical and Chemical properties 

phosphoric acid

Applications

Medicine

The common acid “debility” is very marked in this remedy, producing a nervous exhaustion. A congenial soil for the action of this product 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. Pyros is flatulence, diarrhea, diabetes, rhachitis, and periosteal inflammation. Neurosis in a stump, after amputation. Hemorrhages in typhoid. Useful in relieving the pain of cancer. In dentistry, it may be used in silicate cement, and to, etc H3PO4 enamel and dentin surfaces before application of various types of resins. In may also be used as a dispersing agent in pharmaceuticals

Agriculture

The primary use of this product 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, 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 H3PO4 help to reduce the risk of pipework corroding, prevent the deposit of limescale, control the pH of water.

pH control

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 H3PO4 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. To avoid dangerously high lead content in water from the system, a small number of purified H3PO4 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

it is a common oral supplement by decreasing bone mineral density. Nonsense is used in foods and beverages. The main source of H3PO4 is soda. Very diluted H3PO4 coupled to moderate heating below 90°C to partial hydrolysis of polysaccharides from different phytobiomass sources is feasible and advantageous.

Other usages

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
