Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), also known as orthophosphoric acid or Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), is a weak acid with the chemical formula H3PO4. It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid.All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions (protons). When all three H+ ions are removed, the result is an orthophosphate ion PO43−, commonly called “phosphate”. Removal of one or two protons gives dihydrogen phosphate ion H2PO−4, and the hydrogen phosphate ion HPO2−4, respectively. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) also forms esters, called organophosphates.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.The name “Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat)” can be used to distinguish this specific acid from other “Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat)”, such as pyrophosphoric acid. Nevertheless, the term “Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat)” often means this specific compound; and that is the current IUPAC nomenclature.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is produced industrially by two general routes.[15] In the wet process a phosphate-containing mineral such as calcium hydroxyapatite is treated with sulfuric acid.[16]{displaystyle {ce {Ca5(PO4)3OH + 5H2SO4 -> 3H3PO4 + 5CaSO4v + H2O}}}{displaystyle {ce {Ca5(PO4)3OH + 5H2SO4 -> 3H3PO4 + 5CaSO4v + H2O}}} Fluoroapatite is an alternative feedstock, in which case fluoride is removed as the insoluble compound Na2SiF6. The Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) solution usually contains 23–33% P2O5 (32–46% H3PO4). It may be concentrated to produce commercial- or merchant-grade Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), which contains about 54–62% P2O5 (75–85% H3PO4). Further removal of water yields Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) with a P2O5 concentration above 70% (corresponding to nearly 100% H3PO4). Calcium sulfate (gypsum) is produced as a by-product and is removed as phosphogypsum.To produce food-grade Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), phosphate ore is first reduced with coke in an electric arc furnace, to make elemental phosphorus. Silica is also added, resulting in the production of calcium silicate slag. Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat).The Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) from both processes may be further purified by removing compounds of arsenic and other potentially toxic impurities.Food-grade Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) (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 Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), which would include Coca-Cola, are sometimes called phosphate sodas or phosphates. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in soft drinks has the potential to cause dental erosion.[19] Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.Specific applications of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) include:In anti-rust treatment by phosphate conversion coating or passivation As an external standard for phosphorus-31 nuclear magnetic resonance.In Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) fuel cells.In activated carbon production.In compound semiconductor processing, to etch Indium gallium arsenide selectively with respect to indium phosphide.In microfabrication to etch silicon nitride selectively with respect to silicon dioxide.As a pH adjuster in cosmetics and skin-care products.As a sanitizing agent in the dairy, food, and brewing industries.A link has been shown between long-term regular cola intake and osteoporosis in later middle age in women (but not men).[26] This was thought to be due to the presence of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), and the risk for women was found to be greater for sugared and caffeinated colas than diet and decaffeinated variants, with a higher intake of cola correlating with lower bone density.At moderate concentrations Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) solutions are irritating to the skin. Contact with concentrated solutions can cause severe skin burns and permanent eye damage.[27]Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is a unique inorganic acid electrolyte, which is generally used in fuel cell applications at around 200 °C in order to obtain higher system efficiency where its concentration is over 100%. A matrix, which is made of SiC, is used to retain the hot Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in a cell. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) has advantageous properties as an electrolyte, such as low volatility, good ionic conductivity, stability at relatively high temperatures, carbon dioxide tolerance, and also carbon monoxide tolerance. With all these advantages, there have been several technical electrolyte-related problems with fuel cell stacks. The major issues are volume change, evaporation loss, and electrolyte migration, and these are described in detail. These problems mainly arise due to the fact that Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is a liquid electrolyte under fuel cell operation.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) (H3PO4, also known as Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) or phosphoric (V) acid) is a mineral inorganic acid. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) refers to Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in which the prefix ortho is used to distinguish the acid from related Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), called polyphosphoric acids. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), when pure, is a solid at room temperature and pressure. The most common source of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is an 85% aqueous solution that is colorless and nonvolatile but is sufficiently acidic to be corrosive. Because of the high percentage of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in this reagent, at least some of the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is condensed into Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). For the sake of labeling and simplicity, the 85% represents the acid as if it was all Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). Dilute aqueous solutions of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) exist in the orthoform.Phosphoric acid (H3PO4) can be manufactured using either a thermal or a wet process. However, the majority of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is produced using the wet-process method. Wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is used for fertilizer production. Thermal process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is commonly used in the manufacture of high-grade chemicals, which require a much higher purity. The production of wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) generates a considerable quantity of acidic cooling water with high concentrations of phosphorus and fluoride. This excess water is collected in cooling ponds that are used to temporarily store excess precipitation for subsequent evaporation and to allow recirculation of the process water to the plant for reuse.In the wet process, Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (gypsum, CaSO4), which is separated from the reaction solution by filtration. Some facilities generally use a dihydrate process that produces gypsum in the form of calcium sulfate with two molecules of water (calcium sulfate dihydrate, CaSO4·2H2O). Other facilities may use a hemihydrate process that produces calcium sulfate with the equivalent of a half molecule of water per molecular of calcium sulfate (2CaSO4·H2O). The one-step hemihydrate process has the advantage of producing wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) with a higher concentration of phosphorus pentoxide (P2O5) and less impurities than the dihydrate process. A simplified reaction for the dihydrate process is as follows:In order to make the strongest pDisodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) possible and to decrease evaporation costs, 93% (v/v) sulfuric acid is normally used. During the reaction, gypsum crystals are precipitated and separated from the acid by filtration. The separated crystals must be washed thoroughly to yield at least a 99% (v/v) recovery of the filtered Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). After washing, the slurried gypsum is pumped into a gypsum pond for storage. Water is siphoned off and recycled through a surge cooling pond to the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) process. Wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) normally contains 26%–30% (w/w) phosphorus pentoxide, and in most cases, the acid must be further concentrated to meet phosphate feed material specifications for fertilizer production. Depending on the types of fertilizer to be produced, Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is usually concentrated to 40%–55% (w/w) phosphorus pentoxide by using two or three vacuum evaporators.In the thermal process, the raw materials for the production of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) are elemental (yellow) phosphorus, air, and water. The process involves three major steps: (1) combustion, (2) hydration, and (3) demisting. In the combustion step, the liquid elemental phosphorus is burned (oxidized) in ambient air in a combustion chamber at temperatures of 1650–2760°C (3000–5000°F) to form phosphorus pentoxide:The phosphorus pentoxide is then hydrated with dilute phosphoric acid (H3PO4) or water to produce strong Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) liquid.The final step is a demisting step that is applied to removal of the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) mist from the combustion gas stream before releasing to the atmosphere, which is usually accomplished by use of high-pressure-drop demisters. As always, release to the atmosphere can only be accomplished if the demisted product is a clean and nonpolluting stream.The concentration of phosphoric acid (H3PO4) produced from the thermal process normally ranges from 75% to 85% (v/v). This concentration is required for high-grade chemical production and other nonfertilizer product manufacturing. Efficient plants recover approximately 99.9% (w/w) of the elemental phosphorus burned as the phosphoric acid product.In Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) production, the fluorine released from reactors and evaporators is usually recovered as a by-product that can be sold. The remainder is passed to the condenser that produces a liquid effluent with mostly fluoride and small amounts of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). Closed systems recycle this effluent; in other cases, it is discharged to open waters.The manufacture of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) produces a gypsum slurry that is sent to settling ponds to allow the solids to settle out. About 5 lbs of phosphor-gypsum is generated per pound of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). This phosphor-gypsum contains trace elements from phosphate rock, such as cadmium and uranium. Pond systems are usually fitted with lining systems and collection ditches to maintain control of trace elements and avoid contamination of ground water.The major source of phosphorus in the world is apatite, which is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of hydroxyl (OH−) ions, fluoride (F−) ions, and chloride (Cl−) ions, respectively, in the crystal apatite (Ca5(PO4)3(F,Cl,OH)). Commercially, the most important is fluoroapatite, a calcium phosphate that contains fluorine. This fluorine must be removed for the manufacture of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), but it also can be used to produce hydrofluoric acid and fluorinated compounds.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) esters, for example, tributyl phosphate, (CH3CH2CH2CH2O)3PO are used for the separation of nuclear fuel elements, uranium, zirconium and hafnium, and rare earth elements. Trioctyl phosphine oxide (TOPO), R3PO where R is C8H17) is another solvationg extractant used to recover uranium from wet process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) liquors (Hudson, 1982). It is also used as a constituent of supported liquid membranes to recover rhenium from hydrometallurgical effluents (to be described in Chapter 12). Some long chain ketones, for example, methyl isobutyl ketone, CH3CO,CH2CH(CH3)2 have been used for separation of niobium and tantalum (described in Chapter 10).Conductivity An increase in Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) doping levels results in a clear increase in membrane conductivity related to the increase in proton ‘carriers’. Thus at 150 °C, for doping levels of 4.7, 6.7, and 14.5 Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, respective conductivities of 18, 22, and 79 mS cm−1 were obtained. On the contrary, it was observed that membrane conductivities increase up to 150 °C and then decline. This behavior was attributed to the self-dehydration of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) above 150 °C, resulting in less conductive pyrophosphoric acid.At a doping level corresponding to the maximum protonation of PBI, i.e., two Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, the proton hopping from N site to the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) anion was reported to contribute significantly to conductivity, which reached 25 mS cm−1 at 200 °C.On the contrary, at an acid doping level of 5.6 Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, ‘free acid’ contribution to conductivity is dominant. The conductivity of PBI was found to improve with atmospheric humidity, but its dependence on RH was far less than in Nafion membranes. This hopping-like mechanism is confirmed by Arrhenius behavior of conductivity.Hydration, too, releases some additional heat. The properties of phosphorus pentoxide and the absorption process inevitably leave as much as 25% of the oxide plus a Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) mist in the exit gases from the absorption tower. These are captured on passage through an electrostatic precipitator. By variations of the process details and equipment, grades (concentrations) of phosphoric acid from 75–105% (ortho, or superphosphoric acid) H3PO4 may be made in this manner [28].Phosphoric acid production by phosphorus combustion is usually accomplished in a stepwise manner as outlined, with intermediate isolation of the phosphorus. However, it may also be made by direct contact of phosphorus vapor from the furnace of a phosphorus plant with an air stream, and then passing the phosphorus pentoxide produced directly into a hydrator, without collection of the intermediate phosphorus as a liquid. Direct conversion to phosphoric acid in this way is attractive because the bulk of white phosphorus produced is converted to phosphoric acid.What is Phosphoric Acid?
