Phosphoric acid is a phosphorus-containing inorganic acid made up of phosphorus, oxygen, and hydrogen. In a broardened term, it includes the monomeric (orthophosphoric acid), dimeric (pyrophosphoric acid), and polymeric (metaphosphoric acid) forms of the acid. Phosphoric acid commonly indicates the monomeric form orthophosphoric acid. On heating to about 225 C, it dehydrates to form pyrophosphoric acid and to metaphosphoric acid (2HPO3 = P2O5.H2O) at higher temperatures. Pyrophosphates are salts of pyrophosphoric acid and metaphosphates are salts of metaphosphoric acid. Two molecules of orthophosphoric acid are formed when three molecules of water are added to one molecule of phosphorus pentoxide (2H3PO4 = P2O5.3H2O). The pyrophosphates are formed by the loss of 1 molecule of water from 2 moles of an orthophosphate. Pure orthophosphoric acid is a crystalline solid; melting point 42 C; soluble in alcohol, and very soluble in water. Phosphoric Acid violently polymerizes under the influence of azo compounds, epoxides and other polymerizable compounds. It forms toxic fumes of phosphorous oxides when combusted. It is a medium strong acid and attacks metals to release flammable hydrogen gas. Decomposition may occur on contacting with alcohols, aldehydes, cyanides, ketones, phenols, esters, sulfides, halogenated organics compounds.
Phosphoric acid is essential in the body organism as the constituent of bones and teeth as well as in many metabolic process of carbohydrate, fat and protein. Phosphoric acid is abundant in natural foods as the form of free phosphoric acid itself or as the mineral salts (potassium, sodium or calcium). Phosphoric acid is used to acidify foods and beverages. But the continuous and excessive absorption of beverages particularly Coca Cola and Pepsi Cola which contain large amount of phosphoric acid should be limited. Phosphate excretion takes place in the form of calcium phosphate. The excessive amounts of phosphoric acid in the body may cause calcium deficiency which causes poor teeth and weak bone density (osteoporosis). Phosphoric acid is used in pharmaceutical preparations as a solvent and as a gastric acidifier orally. Phosphoric acid is important raw material in industrial field. It is a tribasic acid (having three replaceable hydrogen atoms) which can forms phosphates with either one, two, or all three of the hydrogen by replacing with some other positive ion. The structure of the phosphate anion consists of phosphorus at the center of a tetrahedron defined by a solid bond between one oxygen atom and phosphorus and single bonds for the other oxygen atoms. In this very formal depiction, negative charge is localized on the O atoms of the single P-O bonds. It is used in making fertilizers, electrolytes, electroplating and derusting solutions. It is used in the manufacture of industrial cleaning products, other inorganic and organic phosphoric chemicals, foundry resins, paints, enamels and refractory, antifreeze productions, and textile process materials. It is used in water treatment. Food grade phosphoric acid is used; as a acidulation in soft drink (particularly cola); ph control in imitation jellies; nutrient in production of yeast; bacteria growth control in selected processed foods; flocculating agent for clarification of sugar juices after liming process.

One of the important phosphates is calcium phosphate, Ca3(PO4)2. The most important phosphorus fertilizer is monobasic calcium phosphate, called superphosphate[Ca(H2PO4)2], derived by treating rock phosphate with sulfuric acid (or phosphoric acid). Superphosphate is soluble in water and acts as a carrier of phosphorus needed by plants. Dibasic calcium phosphate (CaHPO4) is used in pharmaceuticals, animal feeds, and toothpastes. Tribasic calcium phosphate, [Ca3(PO4)2] is used as a fertilizer and as a plastics stabilizer. Other important inorganic phosphates include ammonium phosphate [(NH4)2HPO4] used as a fertilizer and fire retardant; trisodium phosphate used in detergents and for softening water; mono and disodium phosphate used for dispersion, sequestration, scale inhibition and preparing baking powders. The salt forms of phosphate polymers is used as a sequestering agent. As phosphate polymers themselves are hydrated in water at high temperature or high pH, and thereby revert to a more simple and stable phosphate form, which can no longer sequester metal ions.
Mono and dibasic phosphate esters produced by the reaction of either alcohols, alcohol ethoxylates or phenyl ethoxylates with polyphosphoric acid or phosphorous pentoxide are anionic surfactants which have the main feature of the stability in alkaline conditions over other surfactants. They have a wide range of properties including outstanding wetting, emulsification, lubrication, coupling activity and detergency. They exhibit the properties of anti-wear and corrosion inhibition either as free esters or in the forms of metal and amine salts. They are used in:
• Heavy duty alkaline cleaning products
• Laundry Detergents
• Emulsion polymerisation
• Textile auxiliaries
• Acid cleaners
• Metal working fluids
• Emulsifiers
• Wetters
• Dispersants
• Water based lubricants
• Intermediate for the synthesis of other anionic surfactants
Phosphoric acid alkyl esters are also used as alkylation agent for nitrogen heterocyclic compounds and as catalysts to produce phenolic and urea resins. They are used flame retarding plasticizers for cellulose esters, lacquers, plastic and vinyl resins as well as as dispersing agents in plastisols. They are used as solvents in liquid-liquid extractants or separation agent of metals. They are is used as heat exchange media and as pigment grinding assistants and antifoam agents.
Abstract
A magnesia-phosphate cement (MPC) paste based on magnesia and potassium dihydrogen phosphate (KH2PO4KH2PO4 or PDP) was prepared with the additions of dipotassium hydrogen phosphate (K2HPO4K2HPO4 or DHP) and borax as set-retarders. The resulting materials were characterized in terms of their setting characteristics, strength properties, hydration products, and microstructures. The replacement of PDP by DHP was found to increase the setting time and reduce the intensity of the exothermic reactions during the initial setting and hardening stages. When the replacement percentage did not reach 50%, substitution of dipotassium hydrogen phosphate for potassium dihydrogen phosphate in the MPC paste could strike a good balance between the speedy strength gains and delayed setting time. The setting time of the MPC system increased from 5 min (without DHP addition) to 180 min with PDP replaced by DHP completely. The addition of borax also led to an extension of the initial hardening period, as indicated by reductions in the early values of compressive and flexural strengths. The phase of hydration product analysis indicated that no new phase appeared with the addition of DHP, only that more unreacted magnesia appeared with increasing DHP contents. The microstructural characteristics of the materials produced were strongly dependent on the level of DHP and borax employed.
Dipotassium hydrogen phosphate (K2HPO4) has been investigated as an excellent salting-out agent to recover (acetone + butanol + ethanol) (ABE) from a prefractionator. The increasing additions of K2HPO4·3H2O to the ABE system under unsaturated conditons show strong salting-out effects on the ABE. This favorable salting-out effect is based on the hydration of the charged ions. The HPO42– ions may destroy the “hydration shell”, but the crescent concentrations of K2HPO4 make positive salting-out effects on the ABE. More acetone, 1-butanol, and ethanol are recovered after higher-level concentrations of K2HPO4 solution are added to the ABE system. Meanwhile, the equilibrium time shortens. A higher temperature can also make the equilibrium time shorter. The smallest amount of K2HPO4 in the organic phase causes no trouble for the (salting-out + distillation) process in an industrial application.

Potassium Persulfate–Based Oxidation of Pyrrolidones
Oxidation of pyrrolidones using a combination of potassium persulfate and dipotassium hydrogen phosphate to obtain a corresponding succinimides was reported by Needles and Whitfield during the 1970s.50 More specifically, when 2-pyrrolidone or N-methyl-2-pyrrolidone were subjected to a combination of potassium persulfate and dipotassium hydrogen phosphate in distilled water at 85°C–90°C, the corresponding succinimide or N-methylsuccinimide were obtained in 61% and 35%, respectively.The mechanism of persulfate-mediated oxidation is postulated through free radical attack on the methylene adjacent to the amide nitrogen. One of the noteworthy features of this method was the selectivity, where the N-methyl position remained unchanged and oxidation occurred only at the α-methylene position.
Example
To a 500-mL round bottom flask was added 2-pyrrolidone or (0.05 mole), potassium persulfate (0.1 mole), dipotassium hydrogen phosphate (0.2 mole) followed by 250 mL of distilled water. Nitrogen gas was bubbled through the reaction mixture for an hour and the reaction mixture was kept under a nitrogen atmosphere throughout the course of the reaction. The reaction mixture was slowly heated to 65°C where an exotherm was observed up to 85°C–90°C. The elevated reaction temperature (85°C–90°C) was maintained for 30 minutes. After completion of reaction, the water was removed from the reaction mixture by distillation. The corresponding succinimides or were isolated after work up.
