Abstract: Compounds and methods are disclosed for reversibly aggregating particles suspended in a liquid medium. The method comprises combining the liquid medium containing the particles with a polyionic polymer capable of aggregating the particles under conditions suitable for such aggregation. Thereafter, the particles are contacted with a chemical reagent capable of cleaving the polyionic polymer under conditions sufficient to reverse the aggregation. Optionally, magnetic particles are added to the liquid medium in the present method under conditions for non-specific binding and the medium including the aggregates is subjected to a magnetic field gradient to separate the aggregates from the medium. The compounds of the present invention are polyions. The aggregation of the particles is reversible upon contact with chemical agents which cleave at least some of the bonds within the polyionic polymer.

Abstract: Active-hydrogen compounds, for example, primary and secondary alcohols or diols, are alkoxylated, for example, ethoxylated, using solid anion-bound metal oxide catalysts, such as, zirconium oxysulfate catalyst. Hydrous zirconium oxide is treated with solutions of sulfate phosphate, nitrate or tetrafluoroborate and calcined in air at 300.degree. to 950.degree. C. to produce highly active heterogeneous alkoxylation catalysts. The amorphous catalysts afford narrow molecular weight products. The catalyst can be removed from the product by filtration and reused with no significant loss in activity. Reaction temperatures of 50.degree. to 140.degree. C. are employed for alkoxylation.

Abstract: Sulfonic acids are reacted with sodium nitrite to form new compositions specifically nitrosyl sulfonates. The nitrosyl sulfonates are useful in reacting with a dye base to form a diazo composition which can in turn react with a coupling agent to form a diazo dye. The nitrosyl sulfonate can also be used to react with an aromatic composition to nitrosoate an aromatic composition. These reactions are particularly useful in the formation of a dispersed dye because the dye can be formed directly in a nonpolar organic solvent and can be used without purification of the dye product. Particularly useful is the nitrosyl dodecyl benzene sulfonate since the formed product is soluble in nonpolar solvents and all reaction products remain in solution and aid with the dyeing of fabrics.
