Abstract:
The present invention provides a non-aqueous electrolyte for use in an electrochemical cell comprising: (a) at least one organic solvent; (b) at least one electrolytically active salt represented by the formula: M' (ZRnXq-n)m in which: M' is selected from a group consisting of magnesium, calcium, aluminum, lithium and sodium; Z is selected from a group consisting of aluminum, boron, phosphorus, antimony and arsenic; R represents radical selected from the following groups: alkyl, alkenyl, aryl, phenyl, benzyl, and amido; X is a halogen (I, Br, Cl, F); m=1-3; and n=0-5 and q=6 in the case of Z=phosphorus, antimony and arsenic, and n=0-3 and q=4 in the case of Z=aluminum and boron. Rechargeable, high energy density electrochemical cells containing an intercalation cathode, a metal anode, and an electrolyte of the above-described type are also disclosed.

Abstract:
A solid, gel type non-aqueous electrolyte for use in an electrochemical cell, the electrolyte including: (a) at least one polymer compound; (b) at least one organic solvent, and (c) at least one electrolytically active salt represented by the formula: M'(ZR n X q-n ) m , in which: M' is selected from the group consisting of magnesium, calcium, and aluminum; Z is selected from the group consisting of aluminum, boron, phosphorous, antimony and arsenic; R represents radicals selected from the following groups: alkyl, alkenyl, aryl, phenyl, benzyl, and amido: X is a halogen (I, Br, Cl, F); m = 2-3; n = 0-5 and q = 6 for Z = phosphorous, antimony, and arsenic, and n = 0-3 and q = 4 for Z = aluminum and boron, wherein the polymer compound, organic solvent, and electrolytically active salt interact to form a non-aqueous electrolyte having a solid, gel type structure. The solid, gel type non-aqueous electrolyte is preferably incorporated into an electrochemical cell further including a metal anode and an intercalation cathode.
Abstract:
Es wird ein Verfahren zur Herstellung von Elementhalogeniden beschrieben, das dadurch gekennzeichnet ist, dass in einem ersten Schritt eine Mischung aus einem Material enthaltend das entsprechende Element und Kohlenstoff oder kohlenstoffhaltigem Material hergestellt wird und diese Mischung mit einem unter den Reaktionsbedingungen gasförmigen Halogen, Halogenwasserstoff oder deren Gemischen in Kontakt gebracht und erhitzt wird, wobei die Energiezufuhr durch ein elektromagnetisches Wechselfeld erfolgt.
Abstract:
The preparation of carrier-free As ensues on a radionucleotide generator (10), starting from a germanium target that is dissolved in a first reaction vessel (8). The carrier-free As eluate is reacted with KI in a second reaction vessel (9), and the product AsI3 is separated out via a solid phase extraction cartridge (11). The reaction of the As eluate can, in addition to iodine, also occur with halogenides Br and Cl. Radiopharmaceuticals and radiotherapeutic agents can be produced from the obtained arsenic halides.

Abstract:
The invention relates to a method for producing elemental halides, which is characterized in that during a first step, a mixture consisting of a material containing the corresponding element and of carbon or carbon-containing material is produced, and this mixture is brought into contact with a halogen, hydrogen halide or mixtures thereof, which are all gaseous under the reaction conditions, and is then heated. The supply of energy ensues via an electromagnetic alternating field.
