摘要： Catalysts such as antimony halides, which are useful in fluorination reactions involving hydrogen fluoride, may be reduced during the reaction and require regeneration. Regenerative oxidation is usually carried out by introducing elemental halogen, preferably fluorine or chlorine, into the reaction mixture. In accordance with the invention elemental halogen is prevented from coming into contact with starting materials or intermediate products which are reactive therewith. This is preferably achieved by withdrawing part of the reaction mixture from the reactor, mixing the withdrawn part with chlorine or fluorine in order to regenerate the catalyst, and thereafter returning the withdrawn part to the reactor.

摘要： The present invention provides a (Bi,Pb)SCCO-2223 oxide superconductor composite which exhibits improved critical current density and critical current density retention in the presence of magnetic fields. Retention of critical current density in 0.1 T fields (77 K, .perp. ab plane) of greater than 35% is disclosed. Significant improvements in oxide superconductor wire current carrying capacity in a magnetic field are obtained by subjecting the oxide superconductor composite to a post-processing heat treatment which reduces the amount of lead in the (Bi,Pb)SCCO-2223 phase and forms a lead-rich non-superconducting phase. The heat treatment is carried out under conditions which localize the lead-rich phase at high energy sites in the composite.

摘要： A method for separating .sup.213 Bi from a solution of radionuclides wherein the solution contains a concentration of the chloride ions and hydrogen ions adjusted to allow the formation of a chloride complex. The solution is then brought into contact with an anion exchange resin, whereupon .sup.213 Bi is absorbed from the solution and adhered onto the anion exchange resin in the chloride complex. Other non-absorbing radionuclides such as .sup.225 Ra, .sup.225 Ac, and .sup.221 Fr, along with HCl are removed from the anion exchange resin with a scrub solution. The .sup.213 Bi is removed from the anion exchange resin by washing the anion exchange resin with a stripping solution free of chloride ions and with a reduced hydrogen ion concentration which breaks the chloride anionic complex, releasing the .sup.213 Bi as a cation. In a preferred embodiment of the present invention, the anion exchange resin is provided as a thin membrane, allowing for extremely rapid adherence and stripping of the .sup.213 Bi. A preferred stripping solution for purification of .sup.213 Bi for use in medical applications includes sodium acetate, pH 5.5. A protein conjugated with bifunctional chelating agents in vivo with the NaOAc, to receive the .sup.213 Bi as it is being released from the anion exchange resin.

摘要： A method of preparing antimony pentafluoride comprising converting antimony compounds to hydroxonium fluoroantimonates by reaction of the antimony compounds with fluorinating material, such as hydrogen fluoride, in the presence of an oxidizing agent, such as hydrogen peroxide, removing water from the reaction product to concentrate the hydroxonium fluoroantimonates and reacting the hydroxonium fluoroantimonates with carbonyl difluoride to produce antimony pentafluoride. In one embodiment the hydroxonium fluoroantimonates are prepared by recovering the antimony from spent alkylation catalyst comprising SbF.sub.5 deposited on silica. The silica can also be recovered and recycled to produce a remanufactured alkylation catalyst.

The process provides fine powders of perovskite-type compounds having a good crystallinity, particularly tetragonal barium titanate, which are useful particularly as raw materials of ceramics for electronic devices.
