Description
Durch Patent 289342 ist die DarstellungBy patent 289342 the illustration is
von Präparaten aus Formaldehyd und Zucker-of preparations made from formaldehyde and sugar
' arten geschützt, indem man Milchzucker unter Zusatz von Glykose schmilzt und mit gasförmigem Formaldehyd behandelt.'species protected by melting lactose with the addition of glucose and with gaseous Formaldehyde treated.
Es wurde nun gefunden, daß man auch zu solchen Verbindungen gelangen kann, wenn man an Stelle gasförmigen Formaldehyd einzuleiten, die Zuckerschmelze mit Formaldehyd abgebenden Körpern, wie Trioxymethylen, Paraformaldehyd o. dgl., behandelt.It has now been found that such compounds can also be obtained if Instead of introducing gaseous formaldehyde, the sugar melt with formaldehyde donating bodies, such as trioxymethylene, paraformaldehyde o. The like. Treated.
Die Ausführung des Verfahrens wird durch folgendes Beispiel dargelegt:The execution of the procedure is illustrated by the following example:
Go Teile Glykose werden im Ölbad bis zum Schmelzen erhitzt, hierauf löst man darin 90 Teile Milchzucker und fügt je nach dem gewünschten Mischungsverhältnis etwa 42 Teile Paraformaldehyd hinzu, indem man gleichzeitig unter Rühren und Erhitzen allmählichGo parts of glycose are heated in an oil bath until they melt, then you dissolve in them 90 parts milk sugar and add about 42 parts depending on the desired mixing ratio Paraformaldehyde is added by gradually stirring and heating at the same time
ao weitere 150 Teile Milchzucker einfüllt, wonach man die klare, leichtflüssige Schmelze auf eine ausgebreitete Schicht der etwa gleichen Gewichtsmenge Milchzucker auslaufen läßt, wodurch ein Ankleben an Kühlgefäße ver-ao another 150 parts of milk sugar is poured in, after which the clear, easily flowing melt is added allows a spread out layer of about the same weight of lactose to run out, which prevents sticking to cooling vessels
»5 mieden wird. Das erkaltete Produkt kann direkt pulverisiert und unter Beimischung geeigneter Stoffe zu Tabletten geformt werden, welche für medizinische Zwecke Verwendung finden sollen. Man kann die Abgase des Schmelzprozesses mit etwa nicht in Reaktion getretenem Formaldehyd in einen zweiten Rührkessel einleiten, welcher mit Zuckerschmelze beschickt ist.»5 is avoided. The cooled product can are pulverized directly and formed into tablets with the addition of suitable substances, which are to be used for medical purposes. You can see the exhaust of the Melting process with any formaldehyde that has not reacted into a second Introduce a stirred kettle, which is charged with molten sugar.
Die Gegenwart des Formaldehyds bedingt den leichten Schmelzfluß, während dagegen ohne Zusatz von Formaldehyd, aber unter sonst gleichen Versuchsbedingungen die oben angeführte Zuckermenge eine kaum verknetbare Masse darstellt. Die im Beispiel erwähnte Paraformaldehydmenge läßt sich noch weiter erhöhen, woraus hervorgeht, daß der Formaldehyd nicht allein an Glykose, sondern auch an Milchzucker gebunden ist.The presence of formaldehyde causes the easy melt flow, while against it without the addition of formaldehyde, but under otherwise identical test conditions as above The amount of sugar listed represents a mass that can hardly be kneaded. The one mentioned in the example Paraformaldehyde can be increased still further, from which it can be seen that the formaldehyde is not only in glycose, but is also bound to milk sugar.
Die erhaltene Schmelze stellt eine durchsichtige, glasartige Masse dar, welche sich ohne Rückstand gleichmäßig in Wasser löst, dagegen bildet das einfache Gemisch von Glykose, Milchzucker und Paraformaldehyd ein weißes Pulver, das sich nur ungleichmäßig in Wasser lösen würde.The melt obtained is a transparent, glass-like mass, which is dissolves evenly in water without residue, on the other hand, the simple mixture of glycose, Milk sugar and paraformaldehyde are a white powder that just turns unevenly in Water would dissolve.
Ρλτεν τ-An Spruch:Ρλτεν τ-An saying:
Abänderung des durch das Hauptpatent 289342 geschützten Verfahrens zur Herstellung von Präparaten aus Formaldehyd und Zuckerarten, darin bestehend, daß man die Schmelze an. Stelle mit gasförmigem Formaldehyd mit Formaldehyd abgebenden Körpern behandelt. . Modification of the manufacturing process protected by the main patent 289342 of preparations made from formaldehyde and sugars, consisting in the fact that you start the melt. Place with gaseous Formaldehyde treated with formaldehyde-releasing bodies. .
