 einenübrigen besitzt das Produkt keine anticoagulierende Komponente. Das Überraschende an dem pharmakologisch-und physiologisch-chemischen Verhalten dieses Poly-y-propylsulfosäureäthers ist auch darin zu suchen, dass es erstmalig gelungen ist, ohne direkte Fixierung der Sulfogruppe an eine Hydroxylgruppe der Hauptkette eine fibrinolytisch und lipämiesenkendeSubstanz zu erhalten. Das Verfahren wird im folgenden durch ein Ausführungsbeispiel belegt. 



   Beispiel : Herstellung eines   Poly--propylsulfosäureäthers   des Inulins,
54 g Inulin werden in 170 ml 2,5 n-Natronlauge eingetragen und homogen   gerührt ;   hierauf werden   inAnteilen   50 g Propansulton in die vorliegende Mischung eingerührt und vor weiterem Zusatz von Propansulton der Eintritt einer Erwärmung abgewartet. Im allgemeinen lässt man die Reaktionstemperatur nicht über 30-40oC ansteigen, sondern kühlt gegebenenfalls zwischendurch. Nachdem das gesamte Propansulton zugefügt ist, lässt man noch   unter Beobachtung des T emperatonerläufes etwa   1/2 h reagieren. 



  Hernach setzt man noch weitere 140 ml Wasser zu, verrührt homogen und versetzt allmählich unter Rühren mit Alkohol ; es bildet sich hiebei eine zusammenhängende helle und zähe Fällung, die durch Abgiessen der Flüssigkeit leicht isoliert werden kann. Man löst unter Rühren neuerlich in Wasser und wiederholt dieFällung zweckmässig mit absolutem Alkohol; der noch immer zähe Kuchen wird nun von der wässerig-alkoholischen Flüssigkeit getrennt und unter Alkohol zerkleinert, so dass schliesslich ein weisses Pulver hinterbleibt, welches sich leicht filtrieren lässt und nach dem Waschen mit absolutemAlkohol im Vakuum über Natriumhydroxyd aufbewahrt wird. Ausbeute : 63 g. Auf Grund der Elementaranalyse handelt es sich um das Natriumsalz eines   Poly-y-propylsulfosäureäthers   des Inulins.

   Die Substanz ist als Alkalisalz in Wasser sehr leicht löslich, indes ist die Verbindung stark hygroskopisch.

 The product also has no anticoagulant component. The surprising thing about the pharmacological and physiological-chemical behavior of this poly-γ-propylsulfonic acid ether is also to be found in the fact that it has been possible for the first time to obtain a fibrinolytic and lipemia-lowering substance without direct fixation of the sulfo group to a hydroxyl group of the main chain. The method is demonstrated below by an exemplary embodiment.



   Example: Production of a polypropyl sulfonic acid ether of inulin,
54 g of inulin are introduced into 170 ml of 2.5 N sodium hydroxide solution and stirred until homogeneous; then 50 g of propane sultone are stirred into the present mixture in proportions and before further addition of propane sultone, warming is awaited. In general, the reaction temperature is not allowed to rise above 30-40 ° C, but is optionally cooled in between. After all of the propane sultone has been added, the reaction is allowed to continue for about 1/2 hour while observing the course of the temperature.



  A further 140 ml of water are then added, the mixture is stirred until homogeneous, and alcohol is gradually added while stirring; a coherent, light-colored and viscous precipitate forms, which can easily be isolated by pouring off the liquid. It is dissolved again in water with stirring and the precipitation is expediently repeated with absolute alcohol; the still tough cake is now separated from the aqueous-alcoholic liquid and crushed under alcohol, so that finally a white powder remains, which can be easily filtered and after washing with absolute alcohol is stored in a vacuum over sodium hydroxide. Yield: 63 g. Based on the elemental analysis, it is the sodium salt of a poly-γ-propylsulfonic acid ether of inulin.

   As an alkali salt, the substance is very easily soluble in water, but the compound is highly hygroscopic.
