Description

Verfahren zur Herstellung von komplexen Thorium X-Verbindungen Bisher konnte das radioaktive Element Thorium X nur in Form seiner .anorganischen Salze, z. B. Chlorid, Nitrat, Sulfat, zur An--#vendung gebracht werden. Diese Tatsache brachte den Nachteil mit sich, daß das Thorium X bei chemischen Umsetzungen immer nur als Salz reagierte und die zu seiner chemischen Natur gehörigen Reaktionen mitmachte.Process for the preparation of complex thorium X compounds so far could the radioactive element thorium X only in the form of its .inorganic salts, z. B. chloride, nitrate, sulfate, can be used. this fact brought with it the disadvantage that the thorium X always in chemical reactions only reacted as salt and took part in the reactions belonging to its chemical nature.

Es ergibt sich für manche Zwecke die Notwendigkeit, Thorium X komplex herzustellen, damit es z. B. bei der Anwendung im Organismus andere Funktionen ausüben kann. Zu diesem Zweck wird gemäß der Erfindung Thorium X, das ja praktisch masselos ist, an ein Erdalkalielement gebunden und dann in an sich bekannter Weise mit Salzen der Dioxybenzoldisulfosäüren, ihren Homologen bzw: Substitutionsprodukten zur Umsetzung gebracht. Man kann also z. B. ein thorium-X-haltiges Calciumcarbonat in eine wässerige Lösung von brenzcatechindisulfosaurem Natrium eintragen und dadurch zur Umsetzung bringen, daß man die Komponenten so lange erwärmt, bis sich das thorium-X-haltige Calciumcarbonat gelöst hat. Darauf scheidet man aus der Lösung das calciumthorium-X-haltige Komplexsalz durch wasserentziehende Mittel aus.For some purposes there is a need to use Thorium X complex produce so that it z. B. exercise other functions when used in the organism can. For this purpose, according to the invention, thorium X, which is practically massless is bound to an alkaline earth element and then in a manner known per se with salts the Dioxybenzoldisulfosäüren, their homologues or: substitution products for implementation brought. So you can z. B. a thorium-X-containing calcium carbonate in an aqueous one Enter solution of sodium pyrocatechol disulphonate and thereby to implement bring that the components are heated until the thorium-X-containing Calcium carbonate has dissolved. Then the calcium thorium-X-containing is separated from the solution Complex salt by dehydrating agents.

Daß sich bei der Umsetzung ein Komplexsalz gebildet haben muß, geht daraus hervor, daß das eingeführte Ca und somit das an dasselbe gekettete Th X mit Hilfe der üblichen Kalkreaktionen (SOda, Oxalsäure usw.) nicht ' mehr nachweisbar ist. Man kann es erst durch Zerstörung des Moleküls (Veraschung) feststellen. Das Rest-Na dagegen ist normail: (ionogen) gebunden. Dieses Verhalten trinkt man am besten durch ein innerkomplexes Ca (Th X) -Salz mit folgender Formel zum Ausdruck: Die Bildung derartiger Komplexsalze basiert auf dem Vorhandensein der Atomgruppierung SO., OH. .The fact that a complex salt must have formed during the reaction is evident from the fact that the Ca introduced and thus the Th X linked to it can no longer be detected with the help of the usual calcium reactions (SOda, oxalic acid, etc.). It can only be determined by destroying the molecule (incineration). The rest of Na, on the other hand, is normail: (ionogenic) bound. This behavior is best consumed through an intra-complex Ca (Th X) salt with the following formula expressed: The formation of such complex salts is based on the presence of the atom group SO., OH. .

Beispiel ro Gewichtsteile hydrochinondisulfonsaures Natrium «erden in 2o Teilen Wasser gelöst. Zu der klaren Lösung gibt man unter Rühren innerhalb etwa einer Stunde in kleinen Anteilen a,5 Gewichtsteile thorium-X-haltiges Calciumcarbonat, bis vollständige Auflösung eingetreten ist. Aus der schwach gelb gefärbten Lösung fällt man in der Hitze das Komplexsalz mit etwa -roo Gewichtsteilen Aceton und erwärmt noch 1/_ Stunde auf dem Wasserbad, wodurch die Ausscheidung vermehrt wird. Man saugt ab, wäscht mit Aceton nach und trocknet am besten im Vakuum. Die Verbindung ist weiß und enthält das gesamte Thorium X.Example ro parts by weight of sodium hydroquinone disulphonic acid dissolved in 2o parts of water. To the clear solution is added while stirring within about an hour in small proportions a, 5 parts by weight of calcium carbonate containing thorium X, until complete dissolution has occurred. From the pale yellow solution the complex salt is precipitated in the heat with about -roo parts by weight of acetone and warmed 1 / _ hour on the water bath, whereby the excretion is increased. Man sucks Wash off with acetone and dry best in a vacuum. The connection is white and contains the entire thorium X.
