  Verfahren zur Darstellung von sekundärem, sulfosalizylsaurem Hexamethylentetramin. 
 EMI1.1 
 beschrieben, welches durch Einwirkung eines Gewichtsteiles Hexamethylentetranin auf zwei Gewichtsteile Sulfosahzylsäure erhalten wird. In dieser Patentschrift ist weiter angegeben, dass die Sulfosalizylsäure mit mehr als einem Äquivalent Hexamethylentetramin nur schlecht kristallisierende und schwer zu reinigende Produkte liefert. Diese Annahme hat sich als irrtümlich erwiesen. Sie ist   zurückzuführen   auf die grosse Wasserlöslichkeit des aus einem Äquivalent Sulfosalizylsäure und zwei Äquivalenten Hexamethylentetramin bestehenden Salzes sowie auf die Neigung desselben,   übersät+igte   Lösungen zu bilden.

   Tatsächlich kann das sekundäre Salz in gut ausgebildeten und beständigen Kristallen erhalten werden, wenn man zwei Äquivalente Hexamethylentetramin auf ein Äquivalent   Sulfosalizylsäure,   zweckmässig in alkoholischer Lösung, einwirken lässt. 



   Beispiel : 7 kg Hexamethylentetramin werden in 44 l siedendem Alkohol gelöst und mit einer Auflösung von   5#5   kg   Sulfosalizylsäure   in   3'5 I   heissem Alkohol versetzt. Beim Erkalten scheidet sich das sekundäre, sulfosalizylsaure Hexamethylentetramin in Gestalt   grosser, wohl-   ausgebildeter Kristalle ab, die abgesaugt und mit wenig Alkohol   gewaschen werden.   Das neue Salz löst sich sehr leicht in Wasser, schwer in Alkohol, Äther, Azeton und   Chloroform. Gegen 180"   schmilzt es unter Gelbfärbung. Die Analyse ergab   6'29% Schwefel   gegen   6'44% der   Theorie. 



   Das sekundäre,   suifosalizylsaurc   Hexamethylentetramin ist wegen seiner grossen Wasserlöslichkeit zu   Spülungen   besser geeignet als das erheblich   schwerer lösliche primäre Salz.   Es wirkt auch, jedenfalls infolge seiner geringeren Azidität, weniger reizend als das primäre Salz. dem es im übrigen in seiner vorzüglichen Wirkung auf die erkrankte   Blase M'hr ahnhch ist.

  Process for the preparation of secondary, sulfosalicylic acid hexamethylenetetramine.
 EMI1.1
 described, which is obtained by the action of one part by weight of hexamethylenetetranine to two parts by weight of sulfozylic acid. This patent also states that sulfosalicylic acid with more than one equivalent of hexamethylenetetramine gives products that are difficult to crystallize and difficult to clean. This assumption has been proven erroneous. It is due to the high solubility in water of the salt, which consists of one equivalent of sulfosalicylic acid and two equivalents of hexamethylenetetramine, and the tendency of the same to form saturated solutions.

   In fact, the secondary salt can be obtained in well-formed and stable crystals if two equivalents of hexamethylenetetramine are allowed to act on one equivalent of sulfosalicylic acid, advantageously in an alcoholic solution.



   Example: 7 kg of hexamethylenetetramine are dissolved in 44 liters of boiling alcohol, and 5 kg of sulfosalicylic acid are dissolved in 3.5 liters of hot alcohol. On cooling, the secondary, sulfosalicylic acid hexamethylenetetramine separates out in the form of large, well-formed crystals, which are filtered off with suction and washed with a little alcohol. The new salt dissolves very easily in water, difficult in alcohol, ether, acetone and chloroform. It melts towards 180 "with a yellow color. The analysis showed 6'29% sulfur against 6'44% of theory.



   The secondary, suifosalicylic acid, hexamethylenetetramine, is more suitable for rinsing because of its high solubility in water than the considerably less soluble primary salt. It is also less irritating than the primary salt, at least because of its lower acidity. which, by the way, is very good in its excellent effect on the diseased bladder. In-
