  • Patent number: 10734664
    Abstract: A method of removing one or more target impurities from crude hydrogen bis(fluorosulfonyl)imide (HFSI) using a crystallization technique. In some embodiments, the method includes contacting the crude HFSI with at least one anhydrous solvent to create a solution. The solution is caused to have a temperature sufficient to cause HFSI in the solution to crystalize while the one or more impurities remain dissolved in the mother liquor of the solution. The crystalized HFSI and the mother liquor containing the one or more impurities are separated to obtained a purified HFSI product. Purified HFSI products are also disclosed, as are systems, such as secondary batteries, incorporating purified HFSI products.

  • Patent number: 8268269
    Abstract: As population density increases, the transportation of hazardous chemicals, including acids and disinfectants, lead to an increased incidence of spills while the consequences of spills become more serious. While solutions of halide acids, hypohalites and halites are safer disinfectants for transportation, handling, storage and use than traditional gaseous chlorine, the manufacturing cost of these disinfectants has here-to-fore limited their use. Economical processes are presented for the manufacture of O2, halogen oxides, halide acids, hypohalites, and halates; as well as polynucleate metal compounds, metal hydroxides and calcium sulfate hydrate (gypsum). The instant invention presents methods and processes that incorporate the use of sulfur. This is while environmental regulators, such as the US EPA, require an increased removal of sulfur from hydrocarbon fuels, thereby creating an abundance of sulfur, such that the refining industry is in need of a way to dispose of said abundance of sulfur.

    Abstract: Most part of an amount of uranium contained in the spent nuclear fuel is removed by making fluorine or a fluorochemical act on the spent nuclear fuel to convert the uranium into UF6, and the uranium is purified through a simple method of distilling the UF6 together with a absorbent. After removing the most part of the amount of uranium, the remaining nuclear fuel material is dissolved and then transferred to an extraction process to recover plutonium. By doing so, a small sized dry process can be employed as a uranium purification process. Since the nuclear fuel material is dissolved and extracted after removing most part of an amount of uranium, a volume of processing solution can be reduced and the machine installation scale can be made small. Accordingly, the reprocessing facility can be extremely downsized.

  • Patent number: 5498400
    Abstract: A process to manufacture high purity thionyl chloride and phosphorus oxychloride utilizing a fluctuating flow of sulfur dioxide. Chlorine, sulfur dioxide, and phosphorus trichloride are reacted in a process that limits the amount of sulfuryl chloride and/or phosphorus trichloride remaining in the product stream. Cl.sub.2 and SO.sub.2 are first reacted to form SO.sub.2 Cl.sub.2, which, in turn, is reacted with excess PCl.sub.1 to form the products, POCl.sub.3 and SOCl.sub.2. Any excess PCl.sub.3 is then reacted with additional Cl.sub.2 and SO.sub.2 to form additional product. Alternatively, Cl.sub.2, SO.sub.2, and PCl.sub.13 are reacted directly to form POCl.sub.3 and SOCl.sub.2 without the formation of any SO.sub.2 Cl.sub.2 intermediate by utilizing a continuous stirred loop reactor.

  • Patent number: 5430234
    Abstract: Unreacted phosphorus and heavy metals, such as arsenic and antimony, are removed in environmentally acceptable form from the non-aqueous still bottoms residue resulting from the production of PCl.sub.3, by reacting the residue with an excess of calcium hydroxide in the form of an aqueous lime slurry and separating the reaction product into a precipitate and a filtrate. The reaction with lime slurry may be preceded by hydrolysis with water. The precipitate passes the Toxicity Characteristic Leaching Procedure (TCLP) test and the filtrate contains less than 5 ppm of the heavy metals, thus permitting disposal by landfill and sewering, respectively, under EPA regulations.

  • Patent number: 5310529
    Abstract: There is disclosed an improved process for the preparation of phosphorus trichloride wherein elemental phosphorus is caused to react with chlorine. The improvement comprises continuous, high speed analysis of the contents of the reactor whereby the reaction is controlled to produce less phosphorus pentachloride and other by-products. The analysis is performed by a laser Raman spectrometer associated with an optrode having a remotely located probe head and a circulating sampling system to continuously provide fresh sample to the probe head continuously. Also disclosed is apparatus for the automatic control of the reaction by control of the reactant feed to the reactor in response to the on-line, continuous analysis of the reactor contents.

  • Patent number: 5252306
    Abstract: There is disclosed an improved process for the semi-continuous production of phosphorus trichloride by the reaction of elemental phosphorus and chlorine in a liquid phosphorus trichloride layer. In accordance with the present invention periodic termination of the process by discontinuing phosphorus feed thereby creating a heel containing residual phosphorus is rendered more safe and less waste is produced by the improvement which comprises chlorinating the residual phosphorus at a substantially constant flow rate and continuing the chlorine feed rate until after observing at least one of either a step-wise decrease in the pressure within the reactor or a step-wise decrease in the flow rate of phosphorus trichloride removed from the reactor and then terminating the chlorine feed when said pressure and flow rate achieve a substantially steady state at a lower value.
