Abstract: This invention relates to microspheres produced by spray drying clay slurries and calcining the product to form attrition resistant microspheres. Phosphoric acid is injected in a neutral to mildly alkaline dispersed high solids kaolin slurry immediately before spray drying to improve properties of the microspheres.

Abstract: A catalyst is disclosed for treating gas streams containing organic compounds such as halogenated organic compounds. The catalyst is comprised of vanadium oxide, zirconium oxide and at least one oxide of manganese, cerium or cobalt.Also disclosed is a process for treating gas streams using such catalysts.

Abstract: There is described a novel class of aminegold(III) complexes in which the nitrogen-containing ligand is an alkylamine, an arylamine or a heterocyclic amine. Said complexes are useful in the treatment of tumors in mammals.

Abstract: There are described ionic bis(dicarboxylato)palladate(II) products derived from aliphatic and aromatic dicarboxylic acids useful in the treatment of malignant animal tumors sensitive thereto. Certain of the compounds are novel.

Abstract: There are described platinum-polyhydroxylated amine compounds which exhibit anti-tumor activity in mammalian species. The products are highly soluble in aqueous solutions and they may be administered either orally or in parenteral form.

Abstract: There are described novel bis(thiocyanato)palladium(II) complexes containing bidentate amine ligands. These complexes exhibit an anti-tumor effect against malignant animal tumor cells sensitive thereto and are characterized by low mammalian toxicity.

Abstract: A pharmaceutical composition having as the active ingredient a cis-platinum(II) amine lactate complex in which said amine is derived from ammonia or a monodentate or bidentrate amine ligand such as an alkylamine or alkylene diamine. Said compositions may be administered orally or parenterally and they exhibit pronounced activity against malignant animal tumor cells sensitive thereto.

Abstract: There are described platinum-polyhydroxylated amine compounds which exhibit anti-tumor activity in mammalian species. The products are highly soluble in aqueous solutions and they may be administered either orally or in parenteral form.

Abstract: A pharmaceutical composition in which the active ingredient is an ascorbate complex of platinum (II) coordinated to ammonia, a monodentate amine ligand or a bidentate amine ligand as, for example, an alkylamine, an alkylenediamine or a cycloalkylamine. Said compositions are useful in the treatment of malignant tumors in animals. They may be administered orally or parenterally and they exhibit high solubility in water and low toxicity.

Abstract: Cis-Platinum(II) amine lactate complexes are prepared by reaction of the appropriate platinum(II) amine chloride complex with silver lactate. These complexes possess pronounced anti-tumor activity and low toxicity and thus have high therapeutic indices. They are also highly soluble in water.

Abstract: Non-paraffinic hydrocarbons, such as aromatic hydrocarbons, in a stream of paraffinic hydrocarbons are removed in an operation adaptable for continuous operation by contacting the paraffinic hydrocarbon stream with an oxidation system comprising an aqueous solution of hypochlorite, such as sodium hypochlorite, and a ruthenium species, such as ruthenium dioxide, as the oxidation catalyst. The ruthenium species is oxidized by the hypochlorite to a higher oxidation state with resulting selective oxidation of the non-paraffinic hydrocarbons to water-soluble compounds and/or CO.sub.2. A stream of paraffinic hydrocarbons having a substantially reduced content of or substantially free of non-paraffinic hydrocarbons is recoverable and, if desired, a stream of recovered paraffinic hydrocarbons may be recycled for additional contact with the oxidation system.
