Abstract: Detergent compositions containing water-insoluble aluminosilicate ion exchange materials, organic surface-active agents and a minor amount of silicate solids. The aminosilicate ion exchange materials are characterized by the speed and efficiency with which they are capable of removing hardness ions from the washing liquor. A minor amount of sodium silicate solids is used to provide effective corrosion inhibition and crispness to the detergent granules. The instant compositions are capable of providing, during conventional laundry cleaning operations, superior performance, particularly appearance benefits resulting from their effective anti-deposition properties.

Abstract: An ion exchange substance formed of a porous mineral support having a specific surface area greater than 10 sq.m/g and an organo silicon compound containing at least one amine group in an organic group attached to the silicon atom grafted onto the porous mineral support via the silicon atom of the organo silicon compound and an oxygen group on the support and in which the terminal radicals on the amino group are alkyl groups having from 1 to 3 carbon atoms.

Abstract: Process for improving the water wettability of natural or synthetic zeolites, said process comprising thoroughly mixing at least one natural zeolite, synthetic zeolite or mixture of natural and synthetic zeolites with an aqueous solution of a treating agent selected from the group consisting of at least one polyelectrolytic polycarboxylic acid, at least one completely or partially neutralized polycarboxylate, or at least one mixture of said polycarboxylic acid and polycarboxylates; wherein said treating agent has at least about 40 basic mole percent carboxyl or carboxylate groups and a mean degree of polymerization (numerical mean) between about 3 and about 5000; said mixing conducted at about 0.degree. to about 100.degree.C for at least about 5 minutes; said aqueous solution employed in a concentration between about 2 and about 800 g polycarboxylic acid or polycarboxylate per liter and in such quantity that it comprises about 0.

Abstract: A sewer waste-water treating agent of superior quality produced by alkali treatment of waste catalyst grains arising from the fluid-bed type catalytic cracking process, said sewer waste-water treating agent being capable of facilitating solid-liquid separation.

Abstract: Detergent compositions based on sodium carbonate as a detergency builder also contain finely divided calcium carbonate having a surface area of at least about meters square metres per gram (m.sup.2 /g), preferably frm about 30 to 100 m.sup.2 /g, together with a detergent active compound or mixture of compounds which does not form during use an insoluble calcium salt. The added calcium carbonate tends to improve the detergency building action of the sodium carbonate, and so increase detergency, whilst inhibiting the tendency for the newly precipitated calcium carbonate to be deposited on the washed fabrics.

Abstract: The present invention relates to detergent compositions comprising certain organophilic clays, which compositions impart a soft feel to fabrics washed therein.

Abstract: An ion exchanger consisting of crushed lignite or brown coal retaining alkali ions, which is obtained by immersing the particles in a dilute caustic alkali solution. The concentration of the caustic alkali ranges from 2 to 20 weight percent, preferably from 3 to 10 weight percent. Following the treatment with the alkali, the system is washed with an acid with a pH of 3 to 7 to remove the alkali liquid. The resultant lignite has less than 4 meq/g, for instance 2.60 to 3.50 meq/g, of sodium ions and exhibits abilities of ion exchange. By treating the alkali treated lignite with hydrochloric acid or sulfuric acid it is possible to retain hydrogen ions, and by using a solution of a calcium salt such as calcium chloride calcium ions can be retained. Thus, calcium ions or potassium ions may be exchanged with cations of a salt of metal of Group second in the periodic table such as calcium, magnesium, barium and zinc.

Abstract: An improved process for the production of silicon dioxide ion exchangers, which comprises the step of reacting silicon dioxide with benzyltrichlorosilane, in the absence of solvent and air, followed by hydrolysis, to produce a benzylated silicon dioxide whose benzyl groups can then be substituted with ion exchange reactive groups in a conventional manner.
