These normally utilize the low- and medium-temperature decomposition of inorganic aluminum salts and hydroxides, or metal-organic compounds of aluminum. Typical precursors include aluminum nitrate and aluminum hydroxides. Hydro-thermal conditions are often applied [8], but colloidal methods (sol-gel) have been extensively studied over the past three decades [9-11]. Recent efforts have been aimed at reducing the particle size of a-Al203, and decreasing the temperature of formation of a-Al203 from transient aluminas to <1000 °C [12]. Results similar to those in sol-gel can be achieved with the use of metal ion-polymer-based precursor solutions. Here, the precursor solution (e.g., nitrate salt) is mixed with a water-soluble polymer, which provides a matrix for the dispersion of cations [13]. [Pg.6]

Bromine can function as a solvent. One of the very few metal bromides that has significant solubiUty in bromine is cesium bromide, 19.3 g/100 g of solution, thus providing a method of separating cesium bromide from the other alkah bromides (12). Aluminum bromide also is reported to have significant solubiUty in bromine but the pubUshed solubiUty values are not in good agreement (13). Bromine serves as the solvent in some brominations of organic compounds, such as 1,2-diphenylethane (14). [Pg.280]

Organic compounds of bromine usually resemble their chlorine analogues but have higher densities and lower vapor pressures. The bromo compounds are more reactive toward alkaUes and metals brominated solvents should generally be kept from contact with active metals such as aluminum. On the other hand, they present less fire hazard one bromine atom per molecule reduces flammabiUty about as much as two chlorine atoms. [Pg.293]

Properties Pure 100% nitric acid is a colorless liquid when hrst prepared, but turns yellow when exposed to light. Has a choking odor. It is a strong, so-called oxidizing acid which under the right conditions will react energetically with virtually all organic compounds will usually attack all metals except aluminum and some stainless steels. Very hazardous chemical. [Pg.32]

Haapakka and Kankare have studied this phenomenon and used it to determine various analytes that are active at the electrode surface [44-46], Some metal ions have been shown to catalyze ECL at oxide-covered aluminum electrodes during the reduction of hydrogen peroxide in particular. These include mercu-ry(I), mercury(II), copper(II), silver , and thallium , the latter determined to a detection limit of <10 10 M. The emission is enhanced by organic compounds that are themselves fluorescent or that form fluorescent chelates with the aluminum ion. Both salicylic acid and micelle solubilized polyaromatic hydrocarbons have been determined in this way to a limit of detection in the order of 10 8M. [Pg.229]

The CFX MiniFix technology can treat solids, sludges, and most liquids. The treatment is applicable to a variety of heavy metals such as aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, hexavalent chromium, iron, lead, manganese, mercury, nickel, selenium, silver, thallium, and zinc. The technology also treats organic compounds with high molecular weights. [Pg.452]

The main methods of reducing ketones to alcohols are (a) use of complex metal hydrides (b) use of alkali metals in alcohols or liquid ammonia or amines 221 (c) catalytic hydrogenation 14,217 (d) Meerwein-Ponndorf reduction.169,249 The reduction of organic compounds by complex metal hydrides, first reported in 1947,174 is a widely used technique. This chapter reviews first the main metal hydride reagents, their reactivities towards various functional groups and the conditions under which they are used to reduce ketones. The reduction of ketones by hydrides is then discussed under the headings of mechanism and stereochemistry, reduction of unsaturated ketones, and stereochemistry and selectivity of reduction of steroidal ketones. Finally reductions with the mixed hydride reagent of lithium aluminum hydride and aluminum chloride, with diborane and with iridium complexes, are briefly described. [Pg.302]
