Aluminum sulfate, anhydrous

Anhydrous aluminum sulfate [10043-01-3] Al2(S0 2> is a specialty item used ia food appHcations. [Pg.174]

Hydrates. Aluminum sulfate hydrates, Al2(SO H20, where n ranges from 0 to 27 have been reported (3—6). Relative decreasiag vapor pressure studies iadicate the presence of an octadecahydrate, hexadecahydrate, dodecahydrate, dihydrate, and the anhydrous salt, assumiag that basic aluminum sulfates are not formed duriag the dehydration (3). [Pg.174]

Evaporation of solutions of alumina in sulfuric acid yields crystals of A12(S04)3T6H20. If a group I sulfate is also present, the products are alums MA1(S04)2T2H20, in which aluminum exists as [Al(OH2)fi]3+. Analogous selenates but not tellurates have been prepared. Basic salts, e.g. Al2(OH)2(SO4)210H2O, and solids obtained from aluminum sulfate solutions above 100 °C also contain complex ions in which the coordination sphere of Al3+ is occupied by OH groups and/or water molecules rather than sulfate ions. Thermal decomposition of the hydrate A12(S04)3-16H20 yields practically anhydrous A12(S04)3 at 450 °C further decomposition to... [Pg.116]

The polymerisation of dimethylcyclosiloxanes is conducted in the presence of a catalyst, e.g. based on aluminum sulfate and sulfuric acid. The catalyst is used in the form of a paste of mixed dimethylcyclosiloxanes, anhydrous aluminum sulfate and sulfuric acid. The reaction proceeds thus ... [Pg.255]

The dimethylcyclosiloxane blend is polymerised with the catalyst, a mixture of dimethylcyclosiloxanes, anhydrous aluminum sulfate and sulfuric acid in the 10 5 (0.2-K).15) weight ratio. The catalyst is prepared in a special agitator. [Pg.261]

Aluminum Sulfate occurs as a white powder, as shining plates, or as crystalline fragments. It is anhydrous or contains 18 molecules of water of crystallization. Because of efflorescence, the hydrate may have a composition approximating the formula A12(S04)314H20. One gram of the hydrate dissolves in about 2 mL of water. The anhydrous approaches the same solubility, but the rate of solution is so slow that it initially appears to be relatively insoluble. The pH of a 1 20 aqueous solution is 2.9 or above. [Pg.23]

Derivation (1) Leaching of bauxite with caustic soda followed by precipitation of a hydrated aluminum oxide by hydrolysis and seeding of the solution. The alumina hydrate is then washed, filtered, and calcined to remove water and obtain the anhydrous oxide. (2) Aluminum sulfate from coal mine waste-waters is reduced to alumina. [Pg.49]

The aluminum in a 0.910-g sample of impure ammonium aluminum sulfate was precipitated with aqueous ammonia as the hydrous AI2O3 -. H20. The precipitate was filtered and ignited at 1000°C to give anhydrous AI2O3, which weighed 0.2001 g. Express the result of this analysis in terms of... [Pg.334]

Fillers are used in these products to improve mechanical properties or impart flammability resistance. Fillers are frequently silane-treated to further improve mechanical properties. Fillers must have a low moisture (below 0.1%), a low absorption of resin, and are expected to impart thixotropic properties. There are special cases. For example, if peroxyketals are used as initiators, basic fillers have to be used because acidic fillers interfere with cure times and the shelf-life of the composition. Shape and particle size distribution must be considered in filler selection to impart the desired rheological properties. Calcium carbonate is the most popular filler but aluminum trihydrate, anhydrous calcium sulfate, and silica are also frequently used. Barite is well suited to this application, especially if acid...

With titania catalysts the action was much less pronounced. Adkins and Perkins,181 however, conclude from theiv work that normally very little of the ethylene formed in the dehydration of ethanol in the presence of alumina is through the ether stage. Ether may also 880 be prepared by the dehydration of anhydrous ethanol in the presence of aluminum sulfate. [Pg.53]
