  • Patent number: 5360724
    Abstract: One chiral form of a 1-aryl-2-aminopropane is produced in preference to its enantiomer by allowing a 1-arylpropan-2-one to react with a 1-amino-1-phenylethane of predominantly one chiral form and reducing the resultant 1-(1-arylprop-2-ylideneimino)-1-phenylethane to yield phenylethane and a mixture of 1-aryl-2-aminopropanes in which one chiral form thereof is present in preference to its enantiomer. The mixture of 1-aryl-2-aminopropanes then is subjected to the action of an omega-amino acid transaminase which converts one of the two chiral forms of 1-aryl-2-aminopropane into the corresponding arylpropanone which can be separated from the remaining chiral form of the 1-aryl-2-aminopropane.

  • Patent number: 5342973
    Abstract: A silver salt solution suitable for depositing silver on a support in the preparation of silver catalysts is made by reacting a silver compound with a neo-acid, in a hydrocarbon solvent. The reaction is completed under reflux conditions, thereby removing water formed by the reaction and reacting at least 90% of the unreacted acid. Therefore, the solution may be used without further processing to impregnate a porous support, thereby providing a catalyst useful for oxidation of ethylene oxide.

  • Patent number: 5342966
    Abstract: Methods are disclosed for purifying chemiluminescent water-soluble 1,2-dioxetane derivatives suitable for use as reporter molecules in a variety of biological analytical systems, including enzyme-linked immunoassays, nucleic acid probe techniques, and structural determinations. The methods are based upon high pressure, medium pressure or low pressure liquid chromatography using as the stationary phase alkaline pH-stable compositions with the chromatographic characteristics of reversed-phase adsorbents, at alkaline pH values, and in the absence of acid-forming compounds or compounds with an unshared pair of electrons. Desalting of substantially pure water soluble 1,2-dioxetane derivatives may be accomplished by the same chromatographic systems or by molecular sieve chromatography systems, but in the absence of salt buffers. Under some circumstances, purification and desalting may be combined in a single chromatographic step.
