In order to fix the iron and prevent its volatilization as chloride, F. C. Calvert recommended mixing the product before sublimation with acid calcium phosphate or ammonium phosphate, and M. Adler recommended superphosphate. Kecrystal-lization after treatment of the soln. with animal charcoal has also been recommended. The iron is also said to be removed by treating the soln. with a little chlorine (not an excess), then with ammonia, and finally crystallizing the filtered soln. In his work on at. wt., J. S. Stas purified ammonium chloride as followrs ... [Pg.563]

M0NOC.ALCI0 Phosphate—Acid calcium phosphate—Superphosphate nf fime— Ca(H,PO,X —23i—exists in brain tissue and in those animal liquicfs whose reaction is acid. It is also formed when Ca,(PO,)j is dissolved in au acid, and is manufactured, for use as a manure, by decomposing bone-fxsh with H,SO,. It crystallizes in pearly plates very soluble in H,0. Its solutions are acid. [Pg.141]

In making baking powder there should be added to every part of acid sodium carbonate 2238 parts of cream of tartar (acid potassium tartrate) or. 893 part of tartaric acid, or 2.260 parts of acid calcium phosphate. [Pg.131]

Monobasic calcium phosphate, Ca(H2P04)2, is also known as calcium hypophosphite, calcium biphosphate, acid calcium phosphate, monocalcium orthophosphate, and primary calcium phosphate. It usually exists in the form of the hydrate Ca(H2P04)2-H20. It decomposes when heated to 2oo°C (400°F)... [Pg.155]

In the different calcium phosphates, the hydrogen-bonded O—O distance, obtained from infrared data, decreases from phase to phase as a function of acidity. This is corroborated by X-ray diffraction data, which indicate that the phosphate groups in a more acid calcium phosphate occupy a higher percentage of the structural volume, resulting in shorter hydrogen-bonded O—O distances. Table 19.11 presents... [Pg.502]

Chow et al. [22] used spray drying to prepare nanosize hydroxyapatite (HA) particles. They used a nozzle to spray the acidic calcium phosphate solutiou aud an electrostatic precipitator to collect nanosize powder. Their high-resolution transmission electron microscopy (TEM) showed that the particles, some of which were only 5 nm in size, exhibited... [Pg.706]

Both mono- and dicalcium phosphates dissolve incongruently in water, producing phosphoric acid to an extent dependent upon the temperature and the amount of water available. These acid calcium phosphates wiU, with a large excess of water to remove the phosphoric acid, ultimately dissolve and hydrolyse to produce hydroxyapatite which represents the final state of equilibrium. For this reason it can be difficult to obtain the acid calcium phosphates in the highest state of purity from aqueous media, because of surface hydrolysis. The reactions are complex, but they can be represented by eqnalions snch as... [Pg.202]

Urinary excretion of uric acid, oxalic acid, calcium, phosphate, hydroxyproline and cAMP was higher in patients with renal stones than that observed in patients without nephrolithiasis, but the difference was not statistically significant. [Pg.146]

Mould and bacteria outgrowth are traditionally inhibited by the use of, propionic acid or salts of propionic acid. Also, acetic acid, sorbic acid, and acid calcium phosphate are used (Seiler, 1985). [Pg.16]
