  Aqueous soluble mixed complex organic salts of aluminum sulfate - Patent 4077917
The organic compound is selected from the group consisting of an aliphatic alcohol sulfate; an alkylaryl sulfate; an alkyl, aryl or alkylaryl sulfonate; a dialkyl or alkyloxyalkylene sulfosuccinate; an N-acryl-N-alkytaurate; a sulfoalkyl ester of a fatty acid, e.g., an isethionate; and a sulfated ethylene oxide-propylene oxide block polymer.
The neutralized aliphatic alcohol sulfates and alkyl aryl hydrophobe sulfates are formed by neutralizing aliphatic or alkyl aryl sulfuric acids known as acid sulfates, with an appropriate base such as a metal hydroxide or oxide.
The neutralized sulfated ethylene oxide-propylene oxide block polymers which are suitable for preparing the novel mixed complex organic aluminum sulfates may be prepared by reacting propylene oxide with propylene glycol to form a series of polyoxypropylene hydrophobes having molecular weights ranging from about 950 to about 3250.

 Efficient set accelerator for plaster - Patent 6379458
Aluminum sulfate is also known as an accelerator for reducing the set time of other plaster compositions.
However, a disadvantage of the use of aluminum sulfate hydrate in accelerator compositions is that solutions of it in water are relatively corrosive, having a pH of approximately 1.0-1.7 (for 50% solutions).
Addition of the optional aluminum sulfate hydrate material accelerates the hydration rate, and the set of the plaster composition even further so that it is suitable for use on vertical surfaces with a sprayable composition.

 American Elements: Aluminum Sulfate Supplier & Tech Info
Aluminum Sulfate is a moderately water and acid soluble Aluminum source for uses compatible with sulfates.
Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.
Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.

The purpose of the present study was to investigate the in vitro and in vivo effects of aluminum sulfate on delta-aminolevulinic acid dehydratase (ALA-D) activity from the brain, liver and kidney of adult mice (Swiss albine).
In vitro experiments showed that the aluminum sulfate concentration needed to inhibit the enzyme activity was 1.0-5.0 mM (N = 3) in brain, 4.0-5.0 mM (N = 3) in liver and 0.0-5.0 mM (N = 3) in kidney.
The concentrations of aluminum in the brain, liver and kidney of adult mice were determined by graphite furnace atomic absorption spectrometry.

 Tom's of Maine - About Our Products
Aluminum exists in nature as the mineral alunogenite, a class of naturally astringent mineral salts frequently referred to as alum.
Our aluminum sulfate is prepared from bauxite ore and buffered to bring its pH (acidity) closer to that of the skin, making it gentler and less likely to cause irritation.
Aluminum sulfate is buffered to bring it closer to the pH level of the skin so the aluminum bonds with the protein on the outer layer of skin and is not readily absorbed.

  Vase life of Eustoma grandiflorum as affected by aluminum sulfate
The purpose of this work was twofold: first, to compare the cut eustoma flower quality using different concentrations of aluminum sulfate solution, and second, since the mode of action of aluminum sulfate on cut eustoma quality is not known, we studied water uptake and flower fresh weight during vase life.
The role of aluminum sulfate in increasing vase life is not limited to lowering the pH in the vase solution.
Aluminum sulfate in the vase solution can be applied to a commercial floral preservative for cut eustoma flowers.

 ATSDR - Public Health Statement: Aluminum - Draft for Public Comment
Aluminum compounds are used in many diverse and important industrial applications such as alums (aluminum sulfate) in water-treatment and alumina in abrasives and furnace linings.
Aluminum does not appear to accumulate to any significant degree in cow's milk or beef tissue and is not expected to undergo biomagnification, a progressive increase in the concentration of a chemical that is accumulated in the tissues of organisms, as that chemical is passed from the bottom to the top of the food web.
In addition, exposure to the levels of aluminum that are naturally present in food and water and the forms of aluminum that are present in dirt and aluminum pots and pans is generally not harmful.

 Aluminum sulfate manufacture from aluminum dross tailings (US4320098)
The method can be used as a pretreatment in the manufacture of aluminum sulfate from aluminum dross tailings in a continuous flow reaction zone in which the dross tailings prior to reaction with sulfuric acid are pretreated to reduce the more objectionable contaminants contained therein to acceptable levels.
The dross tailings, which are chiefly particles of aluminum oxide, are suspended in an aqueous slurry and the slurry is heated to a temperature from 185°-225° F. and maintained under liquification pressures and sufficient agitation to insure particle-to-particle attrition that removes an aluminum hydroxide coating which would otherwise inhibit the reaction.

 Aluminum from New Millennium Concepts
Aluminum occurs naturally in some waters but is also introduced as aluminum sulfate by some Aluminum water departments to remove fine particles, color and bacteria.
The reason: municipalities in Canada and other countries often use aluminum sulfate, or alum, to remove mineral particles from water in filtration plants-a process that leaves an aluminum residue in the water.

 formula, in chemistry. The Columbia Encyclopedia, Sixth Edition. 2001-05
In addition to showing the actual number of atoms, molecular formulas are also more useful than empirical formulas in that they explicitly show radicals.
Other groups are also shown in molecular formulas, e.g., the water molecules in the mineral chalcanthite (blue vitriol), which consists of cupric sulfate atoms to each of which are attached five water molecules.
In many cases, especially with organic compounds, even the molecular formula does not provide enough information to identify a compound, so that structural formulas are needed.
