Sodium aluminate Usage And Synthesis
Chemical PropertiesSodium aluminate is a white crystalline solid or solution.
UsesSodium aluminate is used in the treatment of industrial and municipal water supplies. It is also an effective precipitant for soluble phosphate in sewage and is especially useful in wastewater having low alkalinity.
Large quantities of sodium aluminate are used in papermaking where it improves sizing, filler retention,and pitch deposition.The addition of sodium aluminate to titanium dioxide paint pigment improves the nonchalking performance of outdoor paints.
Sodium aluminate is widely used in the preparation of alumina-based catalysts. Aluminosilicate can be prepared by impregnating silica gel with alumina obtained from sodium aluminate and aluminum sulfate. Reaction of sodium aluminate with silica or silicates has produced porous crystalline aluminosilicates which are useful as adsorbents and catalyst support materials, ie, molecular sieves.
UsesSodium Aluminate is used in method for producing Zeolite with enhanced Silicon/Aluminum.
PreparationSmall amounts of sodium aluminate are prepared in the lab by fusion of equimolar quantities of sodium carbonate and aluminum acetate, Al(C2H3O2)3, at 800°C. Other methods involve reaction of sodium hydroxide with amorphous alumina or aluminum metal.Commercial quantities of sodium aluminate are made from hydrated alumina, in the form of aluminum hydroxy oxide, AlO(OH), or aluminum hydroxide, Al(OH)3, a product of the Bayer process which is used to refine bauxite, the principal aluminum ore.
Commercial grades of sodium aluminate are obtained by digestion of aluminum trihydroxide in aqueous caustic at atmospheric pressure and near the boiling temperature.
Definitionsodium aluminate: white solid, NaAlO2 or Na2Al2O4, which is insolublein ethanol and soluble in water giving strongly alkaline solutions;m.p. 1800°C. It is manufactured by heating bauxite with sodium carbonate and extracting the residue with water, or it may be prepared in the laboratory by adding excess aluminium to hot concentrated sodium hydroxide. In solutionthe ion Al(OH)4- predominates.Sodium aluminate is used as amordant, in the production of zeolites,in effluent treatment, in glass manufacture, and in cleansing compounds.
ReactionsSodium aluminate, NaAlO2, white solid, (1) by reaction of aluminum hydroxide and NaOH solution, (2) by fusion of aluminum oxide and sodium carbonate, the solution reacts with CO2 to form aluminum hydroxide.
