Dilute alkali

Caustic alkalis. Dilute by drinking much water, followed by vinegar, lemon or orange juice, or solutions of lactic acid or citric acid. Milk may then be given but no emetics.

Elemental composition W 79.30%, 0 20.70%. Tungsten trioxide may be identified by its physical properties or by x-ray diffraction methods. The oxide is either digested in aqua regia or dissolved in caustic alkalies, diluted, and analyzed for tungsten metal (See Tungsten). 

A solution of 40 g. (0.30 mole) of m-aminoacetophenone (p. 7) in 122 ml. of 36% aqueous hydrobromic acid and 120 mb of water is diazotized by treatment at a temperature below 0 , with a solution of 21.2 g. (0.31 mole) of sodium nitrite in 36 ml. of water. Sulfur dioxide is passed into a solution of 54.2 g. of copper sulfate and 27.2 g. of potassium bromide in 250 ml. of water until reduction is complete. Tbe resulting solution of cuprous bromide is added to tbe diazonium salt solution, and after being beated in a water batb for a short period tbe mixture is steam-distilled. The m-bromoacetophenone is extracted from the distillate with ether, and the ethereal solution is washed with dilute alkali, dilute acid, and water. Drying the resulting solution and distilling gives a 54% yield of product, b.p. 131°/16 mm.

The bromide is prepared in the same way as the chloride, is insoluble in organic solvents, and melts at 251 C, It reacts "with alkaline sodium stannite solution, yielding a brick-red compound I., which turns brown on exposure to iightl This decomposition product when extracted with hot benzene gives II., the corresponding mercuric compound to I. It melts at 190° C., is insoluble in water, alkalies, dilute acids, or acetone, readily soluble in benzene or toluene, and is decomposed by concentrated liydrochloric acid. With mercuric chloride or picric acid it gives precipitates, but remains unchanged when boiled with potassium hydroxide, cyanide, or iodide.

Reduced concrete deterioration due to alkali-silica reaction in mixes in which Portland cement has been partially replaced by fly ash has been widely reported (Hobbs, 1986, 1989 Meland, 1986 Shayan et ai, 1996). Fly ash seems to act mainly as an alkali diluter, lowering the amount of available alkalis in the system. The capability to reduce the alkali-aggregate expansion may vary in different ashes, and depends on their own alkali content and fineness. 

Because of the increased polarity of CR over other (i.e., hydrocarbon) rubbers, CR vulcanizates are sufficiently oil resistant for many uses. Also, CR vulcanizates are fairly resistant to chemicals such as concentrated alkalis, dilute acids, and aqueous salt solutions. 

Freitag and Reinking reported on the property profile of Bayer s commercial polyarylate [31], They observed that polyarylate was less sensitive to specimen thickness than polycarbonate in the notched izod impact test. They stated that polyarylate is quite similar to polycarbonate in hydrolytic degradation by alkalis, dilute acids, and hot water. The injection moldability...
