Description

  

  Verfahren zur Gewinnung eines haltbaren     Derivates    der     Cyclohegenyl-äthyl-          bar        bitursäur    e.    Das Hauptpatent betrifft ein Verfahren  zur Gewinnung eines haltbaren Salzes der       Cyclohexenyl-äthyl-barbitursäure,    welches da  durch gekennzeichnet ist, dass man die     Cyclo-          hegenyl-äthyl-barbitursäure    in Gegenwart von  Alkali mit einer     Calciumverbindung    in ihr       Calciumsalz    umwandelt, das gegen den Ein  fluss des Lichtes und des Luftsauerstoffes  nicht nur sehr beständig, sondern darüber  hinaus auch eine schnellere Resorption zeigt.  



  Es wurde nun gefunden, dass man die       Cyclohexenyl-ä,thyl-barbitursäure        auchdadurch     in ein haltbares Salz von ähnlichen Eigen  schaften umwandeln kann, wenn man sie in  Gegenwart von Alkali durch Einwirkung  einer     Magnesiumverbindung    in das     cyolo-          hexenyl-äthyl-barbitursaure    Magnesium über  führt.  



  Das Endprodukt stellt ein in Wasser       schwerlösliches    weisses Pulver dar, das man  durch Zusatz von starken Säuren in die in    Wasser ebenfalls     schwerlösliche        Cyclohexenyl-          äthyl-barbitursäure,    die nach dem Trocknen  den Schmelzpunkt 172   zeigt,     rückverwan-          deln    kann.  



  <I>Beispiel:</I>  25 Gewichtsteile     Cyclohexenyl-äthyl-bar-          bitursäure    werden unter Rühren bei<B>30'</B> in  106 Gewichtsteilen n -Natronlauge gelöst.  Hierzu wird eine Lösung von 12,85 Gewichts  teilen     Magnesiumsulfat    (7     aq)    in 20 Gewichts  teilen Wasser langsam hinzugegeben. Das  sich allmählich abscheidende     Magnesiumsalz     der     Cyclohexenyl-äthyl-barbitursäure    wird mit  Wasser gewaschen und getrocknet.



  Process for the production of a durable derivative of cyclohegenyl-ethyl-bar bituric acid. The main patent relates to a process for obtaining a stable salt of cyclohexenyl-ethyl-barbituric acid, which is characterized by the fact that the cyclohexenyl-ethyl-barbituric acid is converted into its calcium salt in the presence of alkali with a calcium compound, which counteracts the influence of light and atmospheric oxygen is not only very stable, but also shows faster absorption.



  It has now been found that cyclohexenyl-ethyl-barbituric acid can also be converted into a durable salt with similar properties if it is converted into the cyolohexenyl-ethyl-barbituric acid magnesium in the presence of alkali by the action of a magnesium compound .



  The end product is a white powder which is sparingly soluble in water and which can be converted back into cyclohexenylethylbarbituric acid, which is also sparingly soluble in water and which has a melting point of 172 after drying, by adding strong acids.



  <I> Example: </I> 25 parts by weight of cyclohexenyl-ethyl-barbituric acid are dissolved in 106 parts by weight of sodium hydroxide solution at <B> 30 '</B> with stirring. To this end, a solution of 12.85 parts by weight of magnesium sulfate (7 aq) in 20 parts by weight of water is slowly added. The gradually separating magnesium salt of cyclohexenyl-ethyl-barbituric acid is washed with water and dried.

PATENTANSPRUCH: Verfahren zur Gewinnung eines haltbaren Salzes der Cyclohexenyl-äthyl-barbitursäure, dadurch gekennzeichnet, dass man die Cyclo- hexenyl-äthyl-barbitursäure in Gegenwart von Alkali durch Einwirkung einer Magnesium verbindung in ihr 11'Iagnesiumsalz umwandelt. PATENT CLAIM: A process for obtaining a durable salt of cyclohexenyl-ethyl-barbituric acid, characterized in that the cyclohexenyl-ethyl-barbituric acid is converted into its 11'Iagnesium salt in the presence of alkali by the action of a magnesium compound. Das Endprodukt stellt ein in Wasser schwerlösliches weisses Pulver dar, das man durch Zusatz von starken Säuren in die in Wasser ebenfalls schwerlösliche Cyclohexenyl- äthyl-barbitursäure, die nach dem Trocknen den Schmelzpunkt<B>1721</B> zeigt, rückverwandeln kann. Es ist gegen die Einwirkung des Lichtes und des Luftsauerstoffes sehr be ständig. The end product is a white powder that is sparingly soluble in water, which can be converted back into cyclohexenylethylbarbituric acid, which is also sparingly soluble in water and which has a melting point of 1721 after drying, by adding strong acids. It is very resistant to the effects of light and atmospheric oxygen.
