The bones and teeth of humans and other vertebrate animals, for example, consist mainly of a composite material made up of an organic substance, collagen, and a biomineral, calcium carbonate phosphate (see Textboxes 32 and 61). The latter, which makes up about two-thirds of the total dry weight of bone, is composed of calcium phosphate containing between 4-6% calcite (composed of calcium carbonate) as well as small amounts of sodium, magnesium, fluorine, and other trace elements. The formula Ca HPChXPChMCChXOH) approximately represents its composition its crystal structure is akin to that...

Solution (a) Potassium phosphate and silver nitrate are both ionic compounds. Potassium phosphate contains K and PO4 - ions, so its chemical formula is K 4. Silver nitrate contains Ag and NO3- ions, so its chemical formula is AgNOs. Eiecause both reactants are strong electrolytes, the solution contains K, PO4 -, Ag and NO3- ions before the reaction occurs. According to the solubility guidelines in Table 4.1, Ag and P04 form an insoluble compound, so Ag3P04 will precipitate from the solution. In contrast, K" " and NO3- will remain in solution because KNO3 is water soluble. Thus, the balanced molecular equation for the reaction is... 

The condensed phosphates contain more than one phosphorus atom in a molecule but with the structure always built up by PO4 tetrahedra. Whereas in orthophosphates the phosphate tetrahedra are isolated, in condensed phosphates they share corners (but never edges or faces). The larger the O/P ratio in the formula is, the more broken the tetrahedra chains are and the smaller the O/P ratio is, the more cross-linked the chains are (Hong, 1974b). The condensed phosphates can be divided into three groups branched or ultraphosphates cyclic or metaphosphates [P 03 ]" , and chain or polyphosphates [P 03 4i] ". In addition, there is a group of oligophosphates which contain separate anions pyrophosphate, tripolyphosphate, etc., but compounds of the rare earths with these anions have been little studied (Palkina, 1978). The... 

Phosphate Esters. A variety of phosphate esters are used as synthetic lubricants, particularly because of their good fire resistance. They have the general formula OP(OR)2, where R may represent a variety of aryl or alkyl hydrocarbon groups containing four or more carbon atoms to give three broad classes triaryl, trialkyl, and aryl alkyl phosphates (37,38). 

Phosphoric acids and the phosphates maybe defined as derivatives of phosphoms oxides where the phosphoms atom is in the +5 oxidation state. These are compounds formed in the M2O—P20 system, where M represents one cation equivalent, eg, H", Na", 0.5 Ca ", etc. The molecular formula of the phosphoms(V) oxide [1314-56-3] is actually P O q, but this oxide is commonly referred to in terms of its empirical formula, P2O5. StmcturaHy, four phosphoms—oxygen (P—O) linkages are arranged in an approximate tetrahedral configuration about the phosphoms atom in the phosphate anion. Compounds containing discrete, monomeric PO ions are known as orthophosphates or simply as phosphates. 

The trisodium phosphate system is the most complex and the commercial product is generally of variable composition and often contains excess sodium hydroxide. It has long been recognized that the usual formula, Na PO does not accurately represent the constitution of this salt. A better... 

The tertiary metal phosphates are of the general formula MPO where M is B, Al, Ga, Fe, Mn, etc. The metal—oxygen bonds of these materials have considerable covalent character. The anhydrous salts are continuous three-dimensional networks analogous to the various polymorphic forms of siHca. Of limited commercial interest are the alurninum, boron, and iron phosphates. Boron phosphate [13308-51 -5] BPO, is produced by heating the reaction product of boric acid and phosphoric acid or by a dding H BO to H PO at room temperature, foUowed by crystallization from a solution containing >48% P205- Boron phosphate has limited use as a catalyst support, in ceramics, and in refractories. 

Formulas for representative floor poHshes are Hsted in References 3, 12, 13, and 25. An aqueous formula may contain 0—12 wt % polymer, 0—12 wt % resin, 0—6 wt % wax, 0.3—1.5 wt % tris(butoxyethyl)phosphate, 1—6 wt % glycol ether, and 0—1 wt % zinc, with water filling the rest. Water-clear floor finishes contain Htfle or no wax, whereas buffable products contain relatively large amounts of wax. Sealers contain Htfle wax and relatively large amounts of emulsion polymers (28). For industrial use, sealers are appHed to porous substrates to fiH the pores and prevent poHshes that are used as topcoats from soaking into the floor. 

Sohd uranium—phosphate complexes have been reported for the IV and VI oxidation states, as well as for compounds containing mixed oxidation states of U(IV) and U(VI). Only a few sohd state stmctures of U(IV) phosphates have been reported, including the metaphosphate U(P03)4, the pyrophosphate U(P202), and the orthophosphate, CaU(PO4)2. The crystal stmcture of orthorhombic CaU(POis similar to anhydrite (194). Compounds of the general formula MU2(PO4)3 have been reported for M = Li, Na, and K, but could not be obtained with the larger Rb and Cs ions (195). In the sohd state, uranium(IV) forms the triclinic metaphosphate, U(P03)4. Each uranium atom is eight-coordinate with square antiprismatic UOg units bridged by... 

Amines can be blended into multifunctional product formulations containing alkali, polymer, and phosphate and where sulfite- or hydrazine-based oxygen scavengers are part of the formula, but not where tannins are employed. Amines must be fed separately from tannins. 

Despite its relatively late discovery, phosphorus is the eleventh most abundant element in Earth s crustal rock. It has been estimated that world reserves of phosphate rock are sufficient to last for several hundred years. Virtually all phosphorus deposits contain apatite, whose general formula is Caj (P04)3 X, where X — OH, or Cl. Fluoroapatite is the least soluble, hence most abundant, of the three apatite minerals. Phosphorus Is found in aqueous systems as HPOq and H2 PO4 ions. In biological organisms, phosphorus is a component of nucleic acids and energy-shuttling molecules such as ATP. 

Bone is a porous tissue composite material containing a fluid phase, a calcified bone mineral, hydroxyapatite (HA), and organic components (mainly, collagen type). The variety of cellular and noncellular components consist of approximately 69% organic and 22% inorganic material and 9% water. The principal constiments of bone tissue are calcium (Ca ), phosphate (PO ), and hydroxyl (OH ) ions and calcium carbonate. There are smaller quantities of sodium, magnesium, and fluoride. The major compound, HA, has the formula Caio(P04)g(OH)2 in its unit cell. The porosity of bone includes membrane-lined capillary blood vessels, which function to transport nutrients and ions in bone, canaliculi, and the lacunae occupied in vivo by bone cells (osteoblasts), and the micropores present in the matrix. 

Crystalline amino acid bulk solutions are supplied by various manufacturers in various concentrations (e.g., 3.5%, 5%, 7%, 8.5%, 10%, 15%, and 20%). Different formulations are tailored for specific age groups (e.g., adults and infants) and disease states (e.g., renal and liver disease). Specialized formulations for patients with renal failure contain higher proportions of essential amino acids. Formulas for patients with hepatic encephalopathy contain higher amounts of branched-chain and lower amounts of aromatic amino acids. However, these specialized formulations should not be used routinely in clinical practice because their efficacy has not been clearly demonstrated. Crystalline amino acid solutions have an acidic pH (pH = 5-7) and may contain inherent electrolytes (e.g., sodium, potassium, acetate, and phosphate). 

In all cases the reaction products are mixtures of ethyl polyphosphates, and, on the basis of elementary analysis, they approximate the empirical formulas given in the above equations. In Equations 3 and 5 the product has been arbitrarily called hexaethyl tetraphosphate, which may contain 8 to 20% of the active tetraethyl pyrophosphate. In Equations 4 and 6 the products have been called technical tetraethyl pyrophosphate, which may contain up to 40% of pure tetraethyl pyrophosphate. Hexaethyl tetra-phosphate has also been made from phosphoric anhydride and diethyl ether by a process recently patented by Adler (1).

CASRN 12427-38-2 molecular formula C4ff6MnN2S4 FW 265.31 Chemical/Physical. When soil containing maneb was subjected to a stream of moist air, carbon disulfide was formed. Carbon disulfide was also formed when maneb was suspended in a O.IM phosphate buffer at pff 7.0 and air was drawn through the system. The rate of carbon disulfide was higher at neutral and acidic solutions but lower under alkaline conditions. When the air was replaced by nitrogen, no carbon disulfide was evolved. Decomposition products in the reaction vessel identified by TLC were ethylene thiourea, ethylene thiuram monosulfide, elemental sulfur, and trace amounts of ethylenediamine (ffylin, 1973).
