Excess calcium hydroxide is precipitated by usiag carbon dioxide and the calcium carbonate, calcium hydroxide, and calcium phosphite are removed by filtration. The filtered solution is treated with an equivalent amount of sodium sulfate or sodium carbonate to precipitate calcium sulfate or carbonate. Sodium hypophosphite monohydrate [10039-56-2] is recovered upon concentration of the solution. Phosphinic acid is produced from the sodium salt by ion exchange (qv). The acid is sold as a 50 wt %, 30—32 wt %, or 10 wt % solution. The 30—32 wt % solution is sold as USP grade (Table 12) (63). Phosphinic acid and its salts are strong reduciag agents, especially ia alkaline solution (65).

Analysis of a water sample for total solids content (suspended and dissolved) requires evaporation of the water from a measured volume of sample, usually 1 L. For water samples, the residue is usually dried at 180°C, to put calcium sulfate in the anhydrous state, and magnesium sulfate as the monohydrate, MgS04 H2O, in the residue [13]. The level of hydration of many salts varies with the final drying temperature, so this should be stated with the results. 

Thermogravimetric analysis has been widely used to study the thermal decomposition of oxy-salts, such as metal oxalates and metal sulfates. Dollimore, Griffiths and Nicholson have reported TGA data for a wide range of metal oxalates. In an atmosphere of air, these all decompose in three stages, similar to the thermal decomposition of calcium oxalate monohydrate. 

B. 3-(1,1-Dimethylethyl) 4-methyl (S)-2,2-dimethyl-3,4-oxazolidinedi-carboxylate. To a 2-L, three-necked, round-bottomed flask, equipped with a magnetic stirring bar, Clalsen distilling head, thermometer, and reflux condenser protected from moisture by a calcium sulfate-filled drying tube are added a solution of N-Boc-L-serine methyl ester (48.5 g, 0.22 mol) in benzene (770 mL), 2,2-dimethoxypropane (55 mL, 47 g, 0.45 mol), and p-toluenesulfonic acid monohydrate (0.593 g, 3.1 mmol. Note 9). The colorless solution is heated under reflux (oil bath temperature, 110°C) for 30 min, then slowly distilled until a volume of 660 mL is collected over 4 hr when the reaction Is judged to be complete by TLC (Notes 10 and 11). The cooled, amber solution is partitioned between saturated sodium bicarbonate solution (200 mL) and ethyl ether... 

Anyhydrous compounds have important applications in the chemistry laboratory Calcium chloride forms three hydrates—a monohydrate, a dihydrate, and a hexahydrate. As shown in Figure 10.18, anhydrous calcium chloride is placed in the bottom of tightly sealed containers called desiccators. The calcium chloride absorbs moisture from the air inside the desiccator, creating a dry atmosphere in which other substances can be kept dry. Calcium sulfate is often added to solvents such as ethanol and ethyl ether to keep them free of water. 

Electrophoretic mobilities were measured for calcium oxalate monohydrate (COM) in solutions containing macromolecules. Two mucopolysaccharides (sodium heparin and chondroitin sulfate) and two proteins (positively charged lysozyme and negatively charged bovine serum albumin) were studied as adsorbates. 

In a previous paper (11)/ we described the effects of small ionic species on the surface charge of calcium oxalate monohydrate (COM). The effects were detected by measuring the electrophoretic mobility of the particles in the aqueous phase. The influences of the activity of calcium and oxalate ions monovalent electrolytes and sulfate/ phosphate/ pyrophosphate/ and citrate ions on the electrophoretic mobility were studied. It was found that the results could be accounted for hy certain established theories for the electrical double layer/ which is also useful for analyzing the results of the present work.

Sterile agar slants are prepared using the Streptomyces sporulation medium of Hickey and Tresner, J. Bact., vol. 64, pages 891-892 (1952). Four of these slants are inoculated with lyophilized spores of Streptomyces antibioticus NRRL 3238, incubated at 28°C for 7 days or until aerial spore growth is well-advanced, and then stored at 5°C. The spores from the four slants are suspended in 40 ml of 0.1% sterile sodium heptadecyl sulfate solution. A nutrient medium having the following composition is then prepared 2.0% glucose monohydrate 1.0% soybean meal, solvent extracted, 44% protein 0.5% animal peptone (Wilson s protopeptone 159) 0.2% ammonium chloride 0.5% sodium chloride 0.25% calcium carbonate and water to make 100%.

To a stirred mixture of 1.716 g 3-deoxy-L-hexonolactone, 34 mL water, 442 mg calcium hydroxide, 272 mg barium acetate monohydrate, and 170 mg hydrous ferrous sulfate was added 2 mL 30% H2O2, and an additional 2 mL 30% H2O2 was added after 45 min of... 

The worldwide production of lithium in aU forms was 21,1001 in 2006 (see Ref 27, p. 96). Lithium sulfate solutions are obtained by treating certain ores with sulfuric acid. Lithium is also produced from certain brines that have a low magnesium content. In both cases, adding carbonate precipitates lithium carbonate. Mixing a lithium carbonate slurry with calcium hydroxide produces lithium hydroxide, and lithium hydroxide monohydrate is crystallized from the supernatant solution. Lithium hydroxide is the least soluble alkali metal hydroxide, with a maximum concentration of...
