Zusatz zum Patent 240612.*)Addition to patent 240612. *)
Patentiert im Deutschen Reiche vom 1. März 1913 ab. Längste Dauer: 8.Dezember 1925.Patented in the German Empire on March 1, 1913. Longest duration: December 8, 1925.
Nach dem Verfahren des Patents 266122, Zusatz zum Patent 240612, erhält man ein sekundäres
sulfosalicylsaures Hexamethylentetramin, indem man ein weiteres Mol. Hexamethylentetramin
auf das nach dem Verfahren des Hauptpatents 240612 erhältliche primäre sulfosalicylsaure
Hexamethylentetramin
(CH2J6N4-C7H6O6S
einwirken läßt.According to the process of patent 266122, addendum to patent 240612, a secondary sulfosalicylic acid hexamethylenetetramine is obtained by adding a further mole of hexamethylenetetramine to the primary sulfosalicylic acid hexamethylenetetramine obtainable by the method of main patent 240612
(CH 2 J 6 N 4 -C 7 H 6 O 6 S
can act.
Weitere Versuche haben nun ergeben, daß dasselbe sekundäre Salz auch erhalten wird, wenn man von vornherein unter Ausschluß von Wasser 2 Mol. Hexamethylentetramin auf ι Mol. Sulfosalicylsäure, zweckmäßig in absolut alkoholischer Lösung, einwirken läßt.Further experiments have now shown that the same secondary salt is also obtained, if from the outset, with the exclusion of water, 2 moles of hexamethylenetetramine are added ι Mol. Sulphosalicylic acid, expediently in an absolutely alcoholic solution, allowed to act.
7 kg Hexamethylentetramin werden in 44 1 siedendem Alkohol gelöst und mit einer Auflösung von 5,5 kg Sulfosalicylsäure in 3,5 1 heißem Alkohol versetzt. Beim Erkalten scheidet sich das sekundäre sulfosalicylsäure Hexamethylentetramin in Gestalt großer wohlausgebildeter Kristalle ab, die abgesaugt und mit wenig Alkohol gewaschen werden.7 kg of hexamethylenetetramine are dissolved in 44 l of boiling alcohol and with a dissolution 5.5 kg of sulfosalicylic acid in 3.5 l of hot alcohol are added. When it cools down, the secondary sulfosalicylic acid separates Hexamethylenetetramine in the form of large well-formed crystals, which are sucked off and washed with a little alcohol.
