    摘要： An antiinflammatory steroid exhibiting a tendency to crystal growth in suspension in aerosol propellants is contacted with a halogenated hydrocarbon to form a crystalline solvate, which, after removal of some or all of the propellant from the crystals, is reduced to a particle size permitting inhalation into the human bronchial system when dispersed as an aerosol, the micronised crystalline solvate not thereafter exhibiting crystal growth in the aerosol propellant. The solvate is a new composition of matter which has been characterized by I.R. spectra and the aerosol formulation prepared therefrom has valuable therapeutic properties, particularly in the treatment of asthma.

    摘要： A diamond synthesis run containing synthetic diamonds, graphite and catalyst from a high pressure temperature diamond process is treated with bromine to remove substantially all of the graphite. After bromination, the run is subjected to electrolysis to remove the catalyst metals leaving the diamond product for recovery. Some of the diamonds may have a layer of graphite which is exfoliated by further treatment with liquid bromine.

    摘要： The present invention relates to novel agropolymers, which comprise a carbohydrate and/or silica matrix substantially devoid of proteins, tannins and polyphenols and which comprise metal binding reactive sites. A method of producing the agropolymers is also disclosed wherein the agropolymers are derived from plant materials such as seed coats, seed covers, husks, or hulls of various agricultural crops. The agricultural crops typically used to produce the agropolymers include Oryza sativa, Panicum miliaceum, Setaria italica, Cajanus cajan, Vigna mungo, Vigna radiata, Triticum sp., Ricinus communis, Helianthus annus, Gossypium sp., and Arachis sp. The agropolymers of the present invention are capable of purifying aqueous solutions polluted or contaminated with metals and/or ions. Thus, the present invention also discloses a method whereby agropolymers are used in the purification of contaminated water and other aqueous solutions. The agropolymers disclosed herein are useful in several industrial applications including purifying polluted drinking water or ground water.

    摘要： A particulate pre-reduction cobalt supported Fischer-Tropsch synthesis catalyst precursor which comprises a catalyst support impregnated with cobalt, is treated with a pure hydrogen reducing gas, at a first specific feed gas space velocity, SV1, and at a first heating rate, HR1, to obtain a partially reduced precursor. The support contains reducible cobalt oxide in a calcined state and having a formula-unit in which each mole of cobalt atoms is associated with more than 4/3 moles of oxygen atoms and displaying a reducible cobalt oxide specific surface area at least equal to that of Co3O4 spinel. The partially reduced precursor is then treated with a pure hydrogen reducing gas, at a second specific feed gas space velocity, SV2, and at a second heating rate, HR2, to obtain an activated supported Fischer-Tropsch catalyst, with SV2≦SV1 and/or HR2≧HR1; however, when SV2=SV1, HR2≠HR1 and when HR2=HR1, SV2≠SV1.
