摘要： The contaminants level of a mother liquor can be reduced in the process of forming solutions of sodium aluminate and sodium silicate, adding together the two solutions to produce a reaction mixture comprising a mother liquor and an amorphous sodium aluminosilicate, reacting the reaction mixture to form a zeolite composition containing zeolite A, recovering the zeolite and recycling the mother liquor. This can be done by heating the zeolite A in the reaction mixture to produce a sodalite type product and recovering that sodalite type product as part of the zeolite composition.

摘要： A new silica is formed by hydrothermally reacting an aqueous dispersion of silica and sodium hydroxide, under certain conditions, to form a partly polymerized silicate; spray drying the mixture to form spheres of polysilicate; reacting the polysilicate with sulfuric acid to form a synthetic amorphous silica; and filtering, washing and drying the synthetic silica. This silica is useful as an adsorbent in polyol purification. When milled and air classified to the proper particle size, it is useful as a polishing agent in dentrifrices and as a flatting pigment in paints.

摘要： The corrosion and staining of unlined aluminum tube surfaces by dentifrices such as toothpastes, particularly when the dentifrices contain therapeutic agents, is substantially prevented by incorporation into the dentifrice of a controlled amount of an alkaline earth metal ion such as calcium ion, in the range of 0.005-0.2 weight percent, and preferably in the range of 0.005-0.070 weight percent of the dentifrice. The alkaline earth metal may be provided from any water soluble alkaline earth metal salt or as a reaction product of the alkaline earth metal salt with an amorphous silica abrasive and/or thickener.

摘要： A method for producing certain novel finely divided amorphous, precipitated alkali metal alumino silicates having a increased ion exchange properties is disclosed. The products of the invention are produced by commingling and precipitating, under certain controlled conditions, dilute aqueous solutions of an alkali metal silicate and alkali metal aluminate. Significant process variables include the chemical composition and concentration of the reactants, the precipitating temperatures and pH, the sequence and rate of the addition of the reactants and the mixing intensity during the precipitation. The amorphous products of the invention have base or ion exchange capacities equal and/or superior to known crystalline zeolitic base exchangers or absorbents and such may be used for water softening. Their use in detergents is also disclosed.

摘要： A method for producing a precipitated silicon dioxide having a new combination of physical and chemical properties is disclosed. The pigments are produced by acidulating a solution of an alkali metal silicate with an acid under controlled precipitation conditions. The aqueous reaction medium comprising the precipitated silica is then post-conditioned by introducing a second silicate solution into the reaction vessel and thereafter adding additional acid to react with the said second silicate solution. By varying the amount of the silicate employed in the post-conditioning step, a product is obtained which has a unique combination of physical and chemical properties including reduced wet cake moisture content, high surface areas and oil absorptions, improved surface activity, friability, wetting characteristics, and the like. The product has particular utility for use as a rubber reinforcing agent because of its increased surface activity and oil absorption, etc. The product, however, may be used in paints, paper, detergents, dentifrice compositions, molecular sieves, and polymeric compositions. An unexpected discovery of the invention involves the production of a rubber reinforcing silica which has a decreased wet cake moisture content. In one particularly advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index and surface area of the product.

摘要： Silica products having very high structure as defined by the ability of the silica material to hold water in its wet cake, high oil absorption, and very high surface area can be produced by controlling the rate of acidulation during their production and maintaining the same at a very low rate during the course of the addition of acid to the solution of alkali metal silicate. The control of the index of refraction of the silica so produced is achieved by introduction of controlled amounts of adduct material such as aluminum sulfate to the acid prior to its introduction to the silicate solution.

摘要： A method for controlling the viscosity of dispersed clay slurries is disclosed. In accordance with the invention, the problem associated with shipping or storing clay slurries in tank cars or tanks, that is, significant increases in the viscosity of the slurry which often results in the formation of a gelled mass, is overcome by the addition of gluconic acid or a salt thereof, such as sodium gluconate. The addition of the gluconic acid or the salt serves to control the viscosity of the clay slurry in a manner such that it remains at a substantially uniform and low level even when the slurry is shipped or stored over extended periods of time. The gluconic acid or gluconate is added to the slurry in relatively small quantities, i.e., up to 5.0 pounds/ton clay and unexpectedly does not affect the properties or characteristics of the clay pigment or product.
